Okay guys so I'm sorry if this is tmi for you but whenever I'm on my period I always get a really sharp rectal pain. It's seriously unbearable and it feels like I'm being stabbed in my butt for a few seconds and then it's completely gone. It a lot of times happens in the morning when I wake up, and afterwards I usually have to go #2. I'm very concerned...there isn't really a warning when it happens except I can feel it build up a second or two before the really excruciating pain builds up. I've told my mom about it and told her that I think I should go to the doctor, but until then, what could it be? I'm very concerned because it's honestly one of the worst pains I've ever felt and it only lasts for a few seconds so taking pills or something doesn't really help.
