My husband and i just tried making a baby. Im not sure if im pregnant or not. We had sex 4 days ago, and i've been having pains in my lower stomach, back pains, a little cramping. 1 day ago i bled a little bit, just like spots. It was brownish color. It stopped, then today happened again. I have irregular periods and i had my period 3 weeks ago. Im not sure whats going on. I cant eat too much without feeling the urge to throw up. Can someone help me please. I took a pregnancy test 1 day ago and it was negative. I understand that it usually takes up to 2 weeks to tell. Anyone?
