So in October, I took the plan B about a week before my periods and my periods came on time: the 28th of October. My periods were really heavy and lasted 5 days. In november I had unprotected sex the 23rd, 24 and 25th. During those days I had a blood discharge and i felt like my periods were coming. So I did not bother to worry about taking another plan b. So After that discharge no periods I was expecting them on the 28th but nothing. I think that discharge probably meant I was ovulating. I have just been having creamy like discharge. I am 5 days late and think I might be pregnant. I already tested a week Whitin unprotected sex and it was negative. I am feeling symptoms of pregnancy. Could I be pregnant or plan B messed up my cycle ?
