Ok so here it goes... this may be a little tmi.

My period was April 3rd it lasted 4 days like always. According to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> app, my o day was the 20th. I had sex on the 17th. We use the pull out method. When he pulled out he noticed blood. I put a pad in. He wasn't rough with me or anything like that so I don't know what caused the bleeding. I was only bleeding maybe 3 days. Could I be pregnant? Could the bleeding have been ovulation bleeding?
