so i am having some period like cramps not really bad but more like aching and tightness like as if my daughter is on my bladder. i called my doctor yesterday she said it sounds like mild contractions to come in and give them urine to see if i have a bladder infection. i drank plenty of water and gaterode and it finally went away only lasted for a good hour. but here i am again feeling like i want to push to empty my bladder but nothing i am a FTM so this is all new to me and earlier when i was getting ready to go to the doctor to give them urine i couldnt stand because it feels like my daughter was right on my cervix. i have my doctors appointment tuesday just getting really nervous my baby moves ALOT when i feel these pains and discomfort.
