I am 17 years old and have only had my period for about two and a half years. I 'm sure that this is an abnormality and, through my internet search. have not found anything even remotely similar to this extremely embarrassing situation. When I have my period, I bleed from my rectum as well. As the title of the thread states, the rectal bleeding only happens while I have my period. Not to be too graphic, but the amount of blood does correlate to the actual menstrual flow. I am aware that I should go to the doctor with this problem, but how do I even bring up this topic with my mother (who I would need to take me to the doctor)? I am going on vacation with my family next week, and although my period is not regular, I am afraid that I will get my period, and be unable to go swimming for the full week (as tampons won't really help in this situation). Has anyone ever heard of this before? Please help if you can.
