Ok so last Sunday I got off my period and had unprotected sex with my bf three days later. Yesterday and today Iv been experiencing things like having to pee a lot, my breast and back are sore, my boyfriend said my breast look bigger, Iv been experiencing period like cramps but I’m not due for my period until next month. Could I be pregnant and if so could I be experiencing pregnancy symptoms this early? Or am I just stressing about it?
