It's normal my son has been head down for a while now drives me crazy sometimes cause it feels so heavy on my lower belly lol but I feel his hiccups near my hip bone or even lower like as if he's in my lady area ahaha
I think it's normal, it's the way baby is positioned I have pelvic pain Aallll the time doctor said its OK, but yeah doesn't hurt to ask doc ;)
Have you mentioned it to your doctor? It can be normal, baby is taking up a lot of space and she may adjust to make you more comfortable later, but I would say it's worth a mention to your doctor. It sounds like you have as you were tested for a UTI- but don't hesitate just to ask if he has any advice on how to make it more comfortable for you.
