If your cervix goes from low and hard a week after you ovulate to very high and a bit softer?
Is this a sign of pregnancy?
Your cervix does not do anything special to indicate you are pregnant. It's supposed to get high and sodft and open around the time you ovulate (mine always got high and soft a day or so after I ovulated), but that's the only thing your cervix can really tell you. The cervix just responds to estrogen, and your estrogen levels aren't going to rise significantly until later in pregnancy.
When you are looking for early pregnancy signs, the only two things you can rely on are hCG and progesterone. You can't tell whether you have levels of hCG without doing a pregnancy test. And high progesterone levels only matter if you are really close to the time you're supposed to start your period and they aren't dropping yet. The only reliable way to determine whether your progesterone is low or high is by charting your basal body temp over time. Your BBT is higher in the presence of progesterone. So if you are within a day or so of starting your period and your BBT hasn't dropped yet, that could mean you are pregnant. However, some women have high BBTs until a day or two after theor period starts, so it isn't a sure thing.
