I had unprotected sex but he did not ejaculate inside me. I took plan b 29 hours later because I was still worried. 3 days later I had brown bleeding for a few days and noticed my vagina was more purple in color. A week or so after that I realized I had a uti and got treatment and I am supposed to start my period this week but I haven't yet. I've had an increase in bloating, acne, and head rushes when I stand up but I'm traveling so those symptoms could also be due to that. Today I noticed I had white discharge that looked kind of membraney? Could I be pregnant?? Please help!
