So my period is going on 3 weeks late. I've had two urine pregnancy tests (one at home clear blue digital and one at the hospital) and they were both negative. Saturday and Sunday I had a VERY light pink blood. I don't wanna call it spotting because it never came out. But it was there when I wiped.. Since Saturday I've been nauseous. Haven't felt good AT ALL! Last night me and my hubby had sex thinking it would make me start my period. because normally it does if my period is late.... and there's nothing. I'm not even "spotting" now. any ideas?????
