It all seems a bit complicated at first, but once you have found your cervix a few times, you get more confident at what you are looking for - And it becomes much quicker.
A general guide to locating your cervix is as follows:-
How To Check Your Cervical Position
Begin checking your cervical position after you have completed your menstrual cycle. When checking your cervical fluid or position - ensure that your hands are clean and fingernails are not rough.
There are a few positions that you can be in to check your cervical position. It will depend on what you feel the most comfortable with. Which ever position you choose should remain consistent throughout the length of your cycle. Some women prefer and have no problem checking while sitting on the toilet - other women find it difficult to locate their cervix in this position during fertile time and may need to either squat down on the floor with knees bent and open or putting one foot upon the bathtub or toilet seat.
With one hand holding back the vaginal lips insert the other hands middle finger into your vagina. Move your finger up until you hit your cervix. It should feel like a rounded cylinder shaped mass within your body.
The position of your cervix will vary within your cycle. It will be low in the first phase and start to rise closer to ovulation and then will lower again after ovulation has occurred. When checking for the first time and are unsure what low or high should feel like, when high your cervix is almost unreachable with you fingertip.
Once charting and have gone the changes your cervical position takes on - you will have a better understanding of what a low, mid and high cervical position is.
