my period is typically normal, last month due to a bad breakup and stress I was 2 weeks late, im going on 6.5 weeks now no period, I have been having unprotected sex, but I took a cheap dollar store test 2 nights ago and it was negative. I have been insanely bloated daily, nauseas throughout the days, severe cramps in my lower stomach and back, severe on and off headaches and im getting worried. I know I will hear from everyone to see a dr. and I will when I have a day off and the money to do so, but im getting worried and not sure what it could be. any advice?
