OK I know in part this is really silly, but it has also been a amazing relief for me, I figured out how to Pee with all this baby in me!
i have been having problems for weeks feeling like my bladder was not emptying all the way and always feeling like i needed to pee badly and only small amounts were coming out (no not really the same way it feels with a UTI) but mostly just feeling unsatisfied with each of way too many trips to the bathroom.
Then I also noticed that sometime I would shift or the babies would and suddenly i would pee tons! its like the babies were cutting off my bladders exit or something.
So i did a little exploration of positions while on the toilet and found the greatest thing!
Sit with a very wide stance on the toilet
Take both hands and place them overlapping on your very low abdomen, right above your pubic hair where you bladder is. if you are carrying very low this step might not be necessary.
Lean forward so you actually lay your belly with your hand trapped in between on the very front of your toilet seat (might not work if you have a split front design and i would never do it on public seat)
the amount of learn or hands can be used to vary the amount of pressure that is placed on your lower abdomen and or bladder or babies.
Not very time but very often i find an angle that either releases my bladder or puts just that right pressure on it or something, but cause i suddenly pee a huge amount and it is such a relief! I will slowly rock the full range of motion i can get a few times and wow, what a difference, it has cut down the amount of times i wake in the middle of the night and in general i have been so much more comfortable.
As strange as it is, i thought i had to share in case it works for anyone else, it really has improved my 3rd trimester of pregnancy
