TMI!!!!! Im sorry but im tired of this:(

I'm 37,weeks and its been like this for a couple of months where all I'm doing is having to use the restroom like all the time anything I put in my mouth water, cereal, anything to eat I go I'm talking The D word and it sucks!! Im the only one here or no is their anything I can do? Anyone gone thru this, any advice will be greatly appreciated.. I just want to eat and drink and not have to use it right away. I'm worried baby isn't gaining enough cuz I'm not eating drink right without me having to go all the time. Thank you and sorry if its gross.
