March 25th was the first day of my last period. On April 2nd my husband and I had unprotected sex, the next two days following I had some cramping. As the days went on, the headaches came and are still present, and I also get waves of nausuosness throughout the day. About a week and half ago I had started spotting, brown discharge some cramping and when I would wipe a few times was very light faint pink, took hpt and was negative. On the 18th of April I started what I thought was my period which would have been a week early which is weird for me, but it lasted just for the day, wasn't light but wasn't heavy, the next day the bleeding was done and I had a doctors appt, they did bloodwork, came back negative. My period was due to start either today or tomorrow and still nothing and no indication of a period. Took two hpt today and yesterday all negative. Could I be pregnant and It be too early to detect still or am I looking to far into it? Please help I feel like I am losing my mind
