I am having pregnancy symptoms, but I had my period. Already took like 3 urine pregnancy test it all came negative. One came positive that is the blood pregnancy test, the girlfriend of my brother helped me with it. She said that she might have done something wrong, and that I might not be pregnant. My breast are getting bigger, same with my nipples they are bigger than usual. Having cramps even though I dont have my period. Extreme backache, feeling dizzy from time to time, having extreme headache when dizziness is absent. Having this bloated tummy. I just want to know if I'm possibly pregnant.
