Hi, I am a 30 year old female. My periods are always pretty regular and usually last about 4 days. The last 3 periods, they have been coming for a day, then disappearing for a day or two, then returning as normal. This time, that occured again, but they haven t really stopped. As I said, Usually they last 4 days. This time I thought they had stopped, they nearly did, then I had bad cramping (which I never have), then they started again. I ve now had them for about 8/9 days. I do have unprotected sex with my boyfriend as we are not opposed to the idea of getting pregnant! Any ideas??
