I'm a 19 year old sexually active female. I have recently been experiencing some brownish discharge. I thought it was menstrual at first; however, my period shouldn't be for a week or two. I am an excessively clean person. I am not on birth control or any antibiotics. This same thing happened to me last month. I had brown discharge with a reddish blood tint for a few days and I missed my period. My period has never been regular and I have often had skipped months. I haven't bothered taking a pregnancy test. Could I be pregnant? Help, Thanks.
