Cervix positioning

Amanda
So I had unprotected sex and he came in me( I know it was a very very bad idea never doing it again) but I usually keep track of my fertile days and infertile days. When we had sex he was hitting my cervix and I could feel that it was very low. Which I had read means that your not ovulating. But my fertile window had just ended which means in my fertile window it's supposed to be higher up. Which I have no clue where it was during my fertile stage because I've never tracked my cervical position until I felt him in me. The only thing I don't understand is now my cervix is so high up that I can't even reach it. Which I don't understand I can't ovulate twice in one month. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says my fertile days is the 6-12 and my ovulation day is around the 11th.(so isn't it supposed to be high those weeks)  But I had sex on the 13th (when it was very low) and already on the 16th my cervix is back up at a high position. Can someone explain this to me I have no clue what to make of it .
