So my last period was sep19 it lasted four days instead of a full five and was 4days early, i hardly bled only when i wiped did i notice blood. I have been having cramps, have vomited several times, feel bloated and fatigued i am picky with what i eat and fragile around smells, urinate frequently and my stomach feels hard in the center and where my waistband is any pressure is uncomfortable and sleeping comfortable is now a chore ill feel hot sometimes and my back will ache horribly i think im pregnant but i have taken three tests and they've came back negative a friend whom is pregnant and my mom both say to wait til October 19th to take another test, could i be pregnant?
