Hi, a while ago I got the birth control shot, I only got it a total of 4 times, I ve gotten my period since but they are never regular and when I get my period I reallly got it. Its been 4 month since I got my period and sometimes I have rectal bleeding , no pain and it only bleeds when I sit on the toliet, usually. I don t know what s wrong, can anyone help? There is also no chance of me being pregnet, I am gay and have not cheated.
