I'm not sure. If it doesn't hurt, I'd not be too concerned. don't think Anal sex could cause that or having a baby that I know of (have had two myself). So, am not sure. Have you had your well check post baby yet? maybe ask then (I had that at 6 weeks, I wasn't allowed t have sex at all until after that time). good luck and if you get any ideas about it, come back and tell us!
