I don't feel that way everytime I stand up, but I do feel that way occassionally. Especially if I have been riding/driving for a while. Yeah, def check with the dr, but I'm pretty sure its just the little one making their presence known! :-)
I have reoccurring uti's I have had 6 with this pg. I would def get your urine checked. It is better to be safe than sorry. It could be the position and weight of the baby. This is the stage where everyday living becomes highly uncomfortable until we give birth! Welcome to pregnancy! I walk and it feels like any minute his head is going to come flying out it's very very painful and uncomfortable! Ouch. I hope you feel better soon.

Def. talk to your dr. and make sure you don't have a UTI or something. At my birthing classes they said to do kegal excersices to strengthen the bladder. I have a really tiny bladder and pee all the time, but for the most part I am so far controlling it somewhat ok.
I don't have this problem everytime I stand up, but when I do have to pee, it feels UNCONTROLLABLE! I don't think it's anything to worry about, considering the baby is so big on your bladder, there's a good explanation to why you have no control over your bladder. I would still talk to your doctor about it just to make sure though.
