Cervical Position

During your cycle, your cervix changes position. Monitoring cervical position can help you predict ovulation. Observe your cervical position as a daily part of fertility charting - and you can do this in conjunction with monitoring cervical mucus. Try to examine yourself at the same time every day.

When conducting any self-exam, make sure that your hands are clean. Gently insert one or two fingers into your vagina - and by reaching back you should be able to feel your cervix. During the exam, ask yourself the following questions. Is the position of the cervix relatively low (easy to reach) or high (less easy to reach)? Does the cervix feel relatively soft or firm? Does the opening of the cervix feel open or closed? Is the cervix dry to the touch - or relatively moist - or very moist? Note that the answers to these questions are relative, so over time you will be able to draw better conclusions about cervical position.

Prior to ovulation, during the first half of your cycle, the cervix will feel relatively firm (like touching your nose) and dry to the touch - and the position of the cervix will be low in your vagina (easy to reach). The entrance of the cervix will feel closed. However, as you approach ovulation, the cervix will become increasingly soft and will increasingly moisten in order to create a more fertile environment for the sperm. The entrance of the cervix will feel open and begin to lift. At the highest point, the cervix may be a bit difficult to reach and the entrance of the cervix will increase in size. The feel of your cervix will be softer - like touching your lip. At this point, you are at your most fertile time. Following ovulation, the cervix begins to return to a firmer state and the entrance will begin to close. Also, the position of the cervix will again drop and become easy to reach.

I have found testing this to be a bit tricky and I don't rely on it as a fertility sign.
