So, my last menstrual cycle started February 26th. It lasted until the 28th. Normal for me. My periods are regular which means I should start on the 26th, but yesterday (15th) I started spotting VERY lightly. It started as just a small maybe quarter sized brownish pink spot on the toilet paper when I went to pee. There hasn't been too much. I put a pad on so I didn't ruin my panties and it only got on the top. It didn't even soak in. There are occasional mild cramps. It stopped for a bit this morning then started back up around 10 and I put another pad on. It did the same . Could it be implantation bleeding or something else. I HAVE had unprotected sex and it was around the time I was apparently ovulating. Anyway. Thanks ahead of tome
