cycle day 65

Janna
I am 20 years old and a virgin. I don't know why AF is so late. I've been regular every since (well I also missed a month of period when I was like 16). Last three weeks I've been experiencing nausea and palpitations.. sometimes I feel like I can't breathe. I don't know what's happening..
P.S. Last Aug my boyfriend and I were fooling, I sat on his naked 🍆 and grinded (no penetration) it happened 3 days after my period. I've been also sleeping late last 3 weeks. I also have facial hairs (long hairs on my chin, it started growing when I was 18 yrs old..) I think I have PCOS or something is wrong with my thyroid.. HELP.. i need advice.
