受孕黄金时期-排卵期，身体出现的迹象

有些女性每月在月经周期的同一天排卵。其他女性可能在每个月的不同日子排卵。它有助于注意表明你正在排卵的迹象。平均月经周期通常在28至32天之间； 因此月经周期为28天的女性通常在第一3至15天之间排卵–；在月经开始后约两周。

大多数女性的常见排卵体征有如下特点，具体的包括：

宫颈粘液(液体)的变化。 宫颈粘液起作用的一个作用是帮助精子通过子宫进入输卵管。当您的宫颈液具有奶油般的稠度，类似于蛋清时，这表明您接近排卵或正在排卵。

基础体温(BBT)的变化。 通常您的体温在排卵前保持一致。当你接近排卵时，你可能会注意到轻微下降，然后在排卵后会立即急剧增加。这种增加表明刚刚发生排卵。通过在几个月内准确跟踪您的BBT，您可以预测排卵何时发生。

颈部位置或紧致度的变化。你可以研究你的身体，找出你的子宫颈通常是什么感觉以及它在排卵期间的变化。在排卵期间，您的子宫颈柔软，高，开放和潮湿，用手指在阴道内感受到它。

排卵的次要症状可能不一致。它们包括：光斑，骨盆一侧轻微痉挛/疼痛，性欲增加，乳房胀痛，腹部胀气，味觉，嗅觉或视力增强。

排卵预测试剂盒(OPKs)是检测尿液中黄体生成素(LH)水平的测试。LH通常在排卵前上升。在一个月内可能的排卵时间内使用排卵预测试剂盒(OPK)可以让女性确定黄体生成素(LH)波动，这样她就可以在排卵前知道排卵期并且可以在排卵前进行性交，排卵期同房被认为是怀孕的黄金时期。

Ovulation

Some women ovulate on the same day of their menstrual cycle every month. Other women may ovulate on different days each month. It helps to pay attention to the signs that will indicate you are ovulating. The average menstrual cycle is usually between 28 and 32 days； therefore women with a 28-day menstrual cycle usually ovulate between days 13 to 15 — about two weeks after the start of the menstrual period.

Common ovulation signs in most women include：

Change in cervical mucus (fluid). One of the roles cervical mucus plays is to help the sperm travel up through the uterus and into the fallopian tubes. When your cervical fluid has a creamier consistency， resembling egg whites， it is a sign that you are near ovulation or are ovulating.

Change in basal body temperature (BBT). Typically， your temperature remains consistent prior to ovulation. As you get closer to ovulation， you may notice a slight decline， and then there will be a sharp increase right after ovulation. The increase is an indication that ovulation has just occurred. By tracking your BBT accurately over a few months， you may be able to predict when ovulation occurs.

Change in cervical position or firmness. You can study your body to figure out what your cervix normally feels like and how it changes during ovulation. During ovulation， your cervix is soft， high， open and wet.

There are secondary signs of ovulation， which may not be as consistent. They include:light spotting， slight cramping/pain on one side of the pelvis， increased sex drive， tender breasts， bloating in the abdomen and a heightened sense of taste， smell or vision.

Ovulation predictor kits (OPKs) are tests that detect the level of luteinizing hormone (LH) in your urine. LH typically rises prior to ovulation. Using an OPK during a range of possible ovulation times during the month allows a woman to pinpoint the LH surge so she knows before ovulation occurs and can have sexual intercourse prior to ovulation， which is considered the best time.
