I think i might be pregnant. I had my period the last time at the end of may. on the weekend of June 5 I had sex with my bf without a condom. Its been 9 weeks, today. I still dont have my period, and Ive taken several home pregnancy tests and they say negative. I started my Birth control two weeks ago, and its been giving me cramps in my lower abdomen. so i stopped. i keep wanting to eat, i feel like im eating alot, and then my body is still always hungry. im super emotional, start crying for no reason. could i be pregnant. i was looking online and some women didnt get a positive tets back until just about 3 months.
