Does the post day affects your cycle? I took the post day exactly a month ago, and I had "sex" if there's a way to say it because I really didn't, he cleaned up himself after being inside of me and he was there for like two seconds. But I'm 4 days late of my period, I'm wondering if it's because of the pill. That happened 12 days ago, still in going to took the pregnancy proof this week. I haven't had any period symptoms until today im kinda feeling them, or I don't know if it's just my mind. I'm going crazy please help me.
