Okay so my fiancé and I decided that we wanted to have a baby so the day after my period ended we had unprotected sex several times that day. It hit around midnight and he changes his mind and doesn't think we are ready. I took the morning after pill the next morning but I know that if you are already pregnant it won't work and lately I've felt really funny. Headaches, back pain, emotional ups and downs, and exhausted constantly. What are the chances I'm pregnant?
