I have the Mirena IUD for 10 months now, my boyfriend and I had unprotected sex and he cam in me 2 days ago, which according to my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period app</a> would have been the day I ovulated, but we also had sex prior to those 2 days and he cam in me. Today I had cramping almost as if my period was coming/about to start. Is that normal? Am I just over thinking something that’s not there? You don’t think I could be pregnant?
