If you don't feel comfortable checking your cervix, that's fine. You can get the same information (estrogen presence) by carefully checking your cervical fluid. Checking your cervix is an optional, secondary fertility sign. It is useful for cross-checking your other signs, but is not strictly essential. As you gain more experience and body awareness as you continue charting, you may feel less squeamish about checking your cervix. Indeed, as you see how your other signs are showing you your fertility status, you may feel more comfortable checking your cervix as well.
