For women who track their cervical position in order to determine fertility, many wonder if there correlation between the position of the cervix and early pregnancy.
Unfortunately, there doesn’t seem to be a simple answer for all women. The position of the cervix during pregnancy does change but not at the same time in all women.
After ovulation, your cervix will drop lower in your vagina and feel firm, like the tip of your nose. During pregnancy, the cervix will rise a bit and become softer, but the timing of this happening will vary from woman to woman. For some, this will happen shortly before their period is due, but for other, this will not happen until quite a while after their pregnancy has been confirmed.
Due to this variation between women, checking the position of your cervix to determine pregnancy is not a reliable indication of whether or not your are pregnant. More reliable ways to find out if you are pregnant is take a sensitive home pregnancy test or by visiting your doctor for a pregnancy blood test.
