Checking your cervix is part of testing your fertility. For women who track their cervical position in order to determine fertility, many wonder if there is a correlation between the position of the cervix and early pregnancy symptoms and diagnosis. Typical cervical changes such as softening and opening are associated with impending ovulation but there are no early changes of the cervix in pregnancy.
You cannot determine from the checking the pregnant cervix alone whether you are pregnant or not. Changes associated with the cervix after pregnancy has occurred usually do not happen until many weeks or even months after you miss your period.
Before you miss your period and before you have a positive pregnancy test, it's quite impossible to diagnose implantation or an early pregnancy by palpating the pregnant cervix and feeling specific cervical changes and thus diagnosing the cervix and pregnancy.
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 pregnant cervix will rise a bit and become softer, but the timing of this happening will vary from woman to woman and making it impossible to diagnose pregnancy from examining the cervix. For some, this will happen shortly before their period is due, but for others, 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 you are pregnant. More reliable ways to find out if you are pregnant is to take a sensitive home pregnancy test or by visiting your doctor for a pregnancy blood test.
