hi am 23. I had an unprotected sex with my guy. He didnt ejuculate it in me, but he feels that a drop or so could have been in reached inside me. I missed my periods for 10 days and I took 2 home pregnancy tests. Both showed negative. Now today I got dark brown discharge then soon changed into bloody discharge (but not as peroids blood). Am feeling so tiered and slight cramp as normal periods cramp. My half napkin is full now with that discharge. I don feel any symptoms of pregnancy like naussea, dizzyness, vomitting, breast pricking etc. Only thing I experience is tieredness. Am I pregnant. Is it symptom of etopic pregnancy??
