Cervix after ovulation.

Please help me! I know all ot of people check their cervix and stuff while TTC. If my cervix goes back to being hard after ovulation does that mean I didn't conceive. I've read online that it remains soft with pregnancy. ..any idea? Been trying to conceive with Endometriosis since February. Getting frustrated. Just broke down and started crying because I don't think it's ever happening for me.
