question: Ok so Sep 25 I had unprotected sex with my bf i took plan b the morning after. Again at the beginning of oct (unprotected) but again took plan b the morning after. I got my period or what I thought was my period oct 9 on time. it seemed pretty normal. It ended about the 12th & the day after I experienced a really bad headache & severe nausea which ended with me vomiting multiple times. the day after that I encountered brown watery discharge like watery watery . So the day after that I took a pregnancy test& it came back negative. So I waited a week & throughout that week I experienced & am still experiencing symptoms (nausea dizziness headaches, horrible fatigue... etc.) I started to randomly get really tired and fall asleep randomly I have uncomfortable stomach pain and aches in my hips & lower back. I took another pregnancy test today and it is still negative. Could the plan b have not worked? & if I am pregnant am I testing too early? If not what else could this be?
