I had sex last month Feb 19th unprotected. I wasn't sure if he pulled out in time. Days later I got a test (4) it was negative. I thought it was still too soon too tell. I've been having cramps in my stomach, dizziness, nausea, breast tingling, and wanted certain foods. I've been pregnant before and I had a moment were in got really nausea and over heated and dizzy. I knew then. But my period came, not on time (and week late). But it's light and blood red. It disn't smell like period. After my period, my breast still tingle (not hurt) and my stomach is always hurting. I'm not certain. I think I could be paranoid making myself feel this way. if not, what could it be? I'm in my early 30s.
