I have been on Sprintec birth control for about 2 years now, and have had relatively normal periods. This month, I have had cramping and usual symptoms, except there is no red blood, only brown gooey stuff, and there s not very much of it either. Is this normal? For reference, I m 18 and sexually active, my partner and I usually use the pull out method in addition to the pill, neither of us have any std s. I take my pill at the same time every day, and haven t had this problem before.
