No period yet! Symptoms , possible late period , but faint negative line on test? My last period was Aug 30- Sep 4, before that my cycle was 24 days and then before that it was 29. I have yet to get my period . I had unprotected sex the 9th and 10th. And I'm experiencing normal period symptoms like breaking out on my face and sore breast (more so than usual)but now lower back pain, insomnia, cramping bellow my belly button and breaking out a little on my chest with tiredness. I took a pregnancy test but it turned up a faint negative (barely readable) . At this point I'm not sure what to do or if I'm pregnant .
