You should look up checking your cervical position during your cycle. If you have never felt your cervix before you probably have no idea what you are feeling for. I have checked cervical position for years now. The way I actually learned what a cervix felt like was from being an EMT for years and having to know when we have a women in labor to check her cervix for dilation, so I had to learn what a cervix felt like. After learning and know what to feel for I felt of my own to see where it was.
During your cycle your cervix changes position and it gets hard and soft. Before your period arrives your cervix will be low in your canal and hard like your nose, or maybe a little harder. After your period is over it will rise up in the canal and close off. You will not be able to feel the dimple in it. As your ovulation approaches your cervix will become more soft like your lips and it will be higher and harder to reach, it will also open to allow the sperm to enter the cervix in order to reach the uterus. After you have ovulated the cervix closes again and begins to form a mucus plug in the dimple, preparing the body in case you become pregnant in order to hold the baby in and keep infection out. If you are not pregnant your cervix will lower once again and become firm getting ready for AF to arrive.
There is also different fluids that are present with this. Right before AF arrives you will have a thick sticky white discharge that is present. It is tacky in consistency. After AF it will be watery and thin and pretty clear. As ovulation approaches that discharges changes to the egg white consistency. Some women get the EWCM after ovulation has occurred, so unless you know your body you will not know how to determine if it happens to you before or after ovulation. Anyway, the EWCM will then turn into a thin milky discharge if your progesterone is increasing. If you are pregnant you will notice more of this type of discharge. If you are not then you will notice the tacky thick discharge return.
A cervix felts like a thumb almost. It is round and almost like a cylinder and you can take your finger and go all the way around it when it is low and hard in the canal. You can feel a dimple in the tip of it.
Hope that helps you out. Knowing your cervix is a very good thing.
