Okay guys. I just got off my birth control last month before I started my period. We did have unprotected sex and only used Plan B the day my IUD got taken out. My period was only at least four days with me spotting for a little the five day. That has to be the shortest period I’ve ever had usually I have one for 7 days. We have continued to have unprotected sex. I recently just puked my guts out but felt fine and like nothing happened. On this app it has me having my period in 14 days. On the Flo app it has me starting at 11 days. Could I possibly be pregnant and have symptoms this early on?
