I had sex January 11th, and was on the pill, had my period on time a week and a half after that. I then had sex February 8th, used a condom because I was no longer on the pill, and had my period on time after that, end of the month. That was the last period I've had. I've taken countless home pregnancy tests all negative. Even got a blood test from my obgyn on April 19th, because of a colposcopy surgery due to a abnormal pap smear in march, and that came back negative. I had sex on April 17th with a condom. It is May 6th still no period. Am supposed to have a bone spur removed this Friday the 11th so I'm a little stressed about the surgery but it's not my first so I don't know if this is stress related. I've never missed a period by this much and I've usually been on the pill but every time I've had sex I've used a condom. What gives?
