I had sex last month and had a scare. The condom broke so about 30 to 45 minutes later I went and got Plan B (it was on the third day of my period). I took it on the 10th of February. My period last month was early (my period is always either super early, early, late or super late). I was due to start around the 15 so I gave this month to start anywhere from the 7th to the 15th. It's now the 18th of March and last night I started bleeding very very lightly. Today I'm picking up a bit more bleeding and a light cramping sensation. I had gone to the doctors March 13th and started taking birth control that night. March 16th my boyfriend came inside me. At the doctors they tested me for pregnancy. Negative plus I tested three times before my appointment. All negative. I've tested two more times after my appointment, once this morning. Still negative. Could it just be plan b screwing with my already screwy period plus starting birth control? Six negative tests... highly unlikely that they are all false right? Could this bleeding and cramping be the start of my period? At this point pregnancy is about 25 to 30% of my worry. 70% of my worry is why my period is being screwy. I have a feeling it's all the hormones I blasted into my body but I'd just like to be sure.
