I am on the pill, for about 5 years now. My periods have always lasted the same amount of time and have consitant flow from month to month. My last period was very light, last only 1.5 day (they usally last 4). Now I am having cramps. Not sharp pains, but contsant, dull cramps. This had never happend to me and not sure the cause. I have made an appt with my pcp, but not until the end of the week. Any thoughts?
