Hi my name is Coleen and I am trying to find out if there is a possibility that I could be pregnant. I had unprotected sex on the 18th and 22nd of Feb. 2007. I then felt cramping in my lower tummy and sides. I am also always very fatigued and my nipples are sore. I started getting cramping in my stomach on the 7th March and I was spotting, light brown. In the wee hours of the next morning I started bleeding, very light not like a regular flow of a period. I am still bleeding the same way now (March 9th 2007) The day before that, it seemed as though it was going to stop but didn't I just continue to bleed light. My period is supposed to come on the 12th of march. Could this be my period that just came early or could I be experiencing implantation bleeding? I really do want to be pregnant. What should I think at this point? Could I be pregnant?
