My boyfriend and I had sex on New Years <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>. No condom, he came inside me. Now, I am on birth control BUT I was on antibiotics at the time. Glow said I was a few days from ovulation that day I had sex. I'm 2 days late as of today. A few days ago I experienced light spotting. Help?!
