My bf and I had sex 2 weeks ago. I had some blood on third day of ovulation that was sort of stringy but I don't know why. Now I have had cramping all week when usually I get cramps the day before and on my period. My period is supposed to start in two days. Is this my period early or is this implantation bleeding?? Not sure what to do but I think it's too early to test still. I already took three tests bc we have been trying for a while! Fingers crossed for me ladies!
