I'm today currently 39 weeks, so one week left for me. When I had my 36 week check up. I was told my little boy was head down in my pelvis and engaged 3/5 and got told the same at my 37 week appointment. My 38 week appointment I got told he had came out of my pelvis and was no longer locked in. ' my question is, can they be muddled up with his head and bum because I drink lots and don't urinate huge amounts like you should towards the end. And I always have a big lump stick out to the right of my belly button which to me is too hard to be a bum.
