Pinpoint the day of ovulation prepare pregnant need to do, we all know, find female ovulation and during ovulation intercourse, the probability of conception will be greatly improved, the most critical is to identify ovulation. Several convenient and simple way is to calculate ovulation recommended below.

Egg female reproductive cells, eggs from the ovaries to produce a monthly side. After egg must mature before discharge from the ovary. Egg in a fluid-filled vesicles mature, this is the follicle vesicles with the image of jellyfish is very appropriate to describe the follicle. Each female ovulation typically every 28 to 35 days once a lifetime of about 400 eggs discharged, but also up to 500 eggs, ovaries and two alternating irregular ovulation. In normal ovulation occurs 14 days before the next menstruation. Egg survival time is generally 12 to 24 hours. Mature follicular diameter may be 20 millimeters.

What is the day of ovulation? As the name suggests is the day of ovulation

Ovulation, menstruation and are affected by the pituitary and ovarian hormones and endocrine cyclical changes, both the length of the period is the same, ovulation occurred in the middle two periods. Women's menstrual cycle long or short, but the time interval between ovulation and the beginning of the next menstruation relatively fixed, usually in about 14 days.

Based on this relationship between ovulation and menstruation, you can press the menstrual cycle to calculate ovulation. Calculation method is counted from the first day of the next menstrual cramps, countdown 14 days or minus 14 days is the ovulation day, 5 days before ovulation day and after four days together is called ovulation. According to the menstrual cycle to calculate ovulation is suitable for women of normal menstrual cycle, but there are always some female friends aunt always less regularity. What do they have any good method for detecting it?

The first: basal body temperature measurement. It is a simple and convenient easy method.

The specific measures are: just woke up every morning to measure your body temperature with a thermometer sublingual, and then recorded. In general, women before ovulation body temperature less volatile, the day of ovulation basal body temperature suddenly reduced, the body temperature will rise after ovulation day, the general rise 0.3-0.5 degrees for more than 12 days. While maintaining the temperature drops again to menstrual cramps. The daily basal body temperature measured marked on the graph paper, month, appeared before the high to low basal body temperature curve of a two-way, two-way curve starts high this day is ovulation. However, according to the basal body temperature can not predict ovulation, but can understand the luteal phase.

Detailed measurements :( traditional early morning to after a well-known domestic hospitals provided sublingual measurement method for example) in advance basis or smart thermometer thermometer ready, set the bed or pillow handy as to place, at night can be a smart thermometer before going to bed wearing.

Device Requirements: Due to changes of basal body temperature is generally reflected in a decimal value, it is suggested the use of precision of at least ± 0.1 ℃ thermometer is measured. Some other specially designed to measure the basal body temperature "thermometer basis", data storage and drawing table features a higher relative price of ordinary electronic thermometer.

Summary: 6 hours of sleep, wake after the thermometer with the entrance (Please send probe placed inside the root sublingual, closed his mouth, to ensure that the correct temperature measurement) for at least 5 minutes (generally 5 to 7 points and the morning, be) taken out to observe temperature thermometer, and a respective location designated dot "●" in the tag table, each of the small dots connected by a line segment, i.e., become the basis of the temperature curve.

Daily measurements recorded daily, and during menstruation, menstrual flow record to observe; normal amount is moderate over time, with 1 a cross "×" mark; large amount over time, denoted "××"; in particular, by the amount is small, with Dayton No. "" mark. Or when there are special circumstances insomnia, cold, abdominal pain, vaginal bleeding, will be described at the corresponding position in the "Remarks" column. Time for examination, treatment or medication, in the "Remarks" column at the corresponding position to take notes, plus a small box in the "↑" indicates the start, plus "↓" indicates the end of time.

Basal body temperature recording paper is sold on the market, there are also online for free download. Paper records are not conducive to carry, when the doctor will often forget to bring, is not conducive to the spread. Now there are many tools APP has a record of basal body temperature, such as our help prepare pregnant basal body temperature there is a good tool for recording.

Second, the cervical mucus observation.

Hormone changes ovulation women will affect the body in many ways, in order to combine sperm and egg to create a better environment for female secretions will also change, mainly cervical mucus is increased, and is clear and transparent, finger touch You will find a drawing phenomenon. In general, when the most obvious feature of this time is ovulation.

But cervical mucus observed to have a certain experience and skills, usually have 2-3 months of practice in order to get more accurate judgment. Cervical mucus changes to be affected by many factors, such as vaginal infections, sexual arousal, vaginal medication and so on.

Third, ovulation test assay.

Ovulation test strips is to generate a peak level hormone (LH) by detecting the corpus luteum, to predict whether ovulation. 24 to 48 hours before ovulation, urine luteinizing hormone (LH) peak appears, ovulation self-test strips, positive results will appear. Specific test method, generally on the ovulation test package has a description (to strictly follow the instructions to do in order to minimize the error). Pregnancy test strip with different is not use the morning urine, and urine as far as possible the same time each day, two hours before the urine collecting water intake should be reduced, due to dilution of the urine will hinder the detection of the LH peak. Then Comparative Law menstrual cycle should be 14 days (i.e., the expected time of ovulation) premenstrual, plus three days after the first three days of this time, measured for six consecutive days; irregular menstruation or, if not normal, it is generally measured at the beginning of the third day after menstruation clean. Until the paper as deep as two bars or first bars further deeper than the second bar, it will be described ovulation within 24 to 48 hours, can refer to other test results are shown in the specification.

Simple, inexpensive, but also more complicated, because it is to the user's own judgment result, there is a certain possibility of wrongful convictions, many users do not know how to see the results.

In addition, the ovulation test is only used to monitor the urine, there are no high levels of LH to predict ovulation is imminent, in addition to LH, LH much like another, and some of the hormones (such as HCG, TSH, FSH) test strips may also be detected, and therefore injection of HCG (such as when ovulation), and other situations that can cause elevated FSH or TSH (thyroid disease and some neurological diseases, and the use of some special drugs), may cause the urine appear high concentrations of non-LH this time by the ovulation test positive, does not mean imminent ovulation.

Even if it is elevated LH, would not necessarily ovulation, there is a rare case called "ovarian luteinizing unruptured syndrome (LUFS)", before these patients have elevated LH ovulation, the follicle can mature, but that is not rupture ovulation. Ovulation test ovulation did not necessarily negative, such as test strips expired or damp failure, before the test drink a lot of water leads to excessive dilution of urine, urine dipstick soaking time is not enough, the end of the test paper to detect engage in counter and so on.

The fourth, the most direct and objective monitoring methods --- B super.

Ultrasound monitoring (b super) generally begin monitoring the 10 days of the menstrual cycle, the follicular diameter changes were observed. Detecting within 16mm every 2 days and monitored daily after reaching 16mm, typically about 18-20mm guide the same room, the same room once again the next day. After ovulation follicles disappear, there will be a small amount of pelvic fluid. This method is reliable, but require continuous monitoring and need to go to hospital every time.

By B-ultrasound, see experienced doctor follicles from small to large out of the process, it can not only detect whether there is a dominant follicle in both ovaries, and also measures the size of the dominant follicle, endometrial thickness , which side ovulation like. Patients precise guidance intercourse time, improve the pregnancy rate.

"For example, women, the left fallopian tube has been cut away some of ectopic pregnancy, in which case, if her left ovary ovulation is not pregnant, it can be done by observing which side of the B-ovulation."

As opposed to abdominal B ultrasound, vaginal ultrasound is more accurate. The biggest drawback B-monitored ovulation is required continuous monitoring and need to go to hospital every time. At present, most hospitals need to go through lengthy queuing process, poor service experience. At present, there are few institutions can provide high-quality follicular monitoring equipment pregnancy-related inspection services, in among the prepared pregnant help a great advantage, especially multi-line services stores, customers can choose the nearest hospital for check-ups, eliminating the need to make an appointment and discharge long line of trouble.
