Okay so mid February i had unprotected sex twice in the same night, with the same guy. We used the withdrawal method though. My period was due around the time i slept with him but i haven't received one since the end of my January cycle. I took a test 2 weeks after the sex but it was negative. Could this of been to early for the test or is there another reason that could be causing my period not to come? Today would be the day i usually start my period however i don't even have any sign of it coming. I do have a few pregnancy symptoms but this could just be coincidence, i have nausea, frequent need to pee and really sore boobs. Do you advise maybe taking another test or just going to the doctors?
