What is going on???

Khyre

So about 2 weeks ago me and my boyfriend had sex & we don’t use condoms because I have the Mirena in. So basically he came inside of me. Now the other day I had 24 hours of light spotting (pink) and did not show up on a pad accompanied with cramps. The next day it was fine but I also had plenty of nausea and some vomiting. I’ve had food aversions and it’s been awful. I also had to pee so bad last night I almost wet myself. That has never happened except when I was pregnant with my son. I don’t get periods anymore but I do still ovulate and get ovulation symptoms. My Bf doesn’t believe I could be pregnant but Im just fed all these symptoms. Please help I just need advice.
