My last period was January 21st, I ovulated on February 4th. I also had unprotected sex that day (more than once) I was suppose to start my period again February 18th, my period is now 26 days late (I would be 7 weeks). I have taken 3 pregnancy test all negative. But Ive been sleeping all day, Ive been having hot flashes, My stomach has been hurting Ive been nauseous, Ive had milky white discharge.. I think thats all. I really do think Im pregnant, but yesterday morning at 7 I woke up cramping (lasted about 10 minutes) like I was on my period so I went to the bathroom and when I wiped there was light pink blood. I havent bled since but I've been cramping on and off.. So I don't know.. And my vag has been really sore..
