Pain in bladder.

I posted this before but nobody said anything :(. I just wanna know has this happened to anyone , I’m 14 weeks pregnant and got tested last week because they have to and also because I told her it was very uncomfortable after peeing, the pain can last up to hours. I got tested and the urine tested for uti. Also had vaginal swab tested for stds and also bv and yeast. They never ended up calling me so I called them and they said everything came back negative, I’m very confused because it’s a painful feeling and I don’t understand how I can possibly be negative for EVERYTHING. Yes I’ve also asked them were they sure because it’s still uncomfortable after I pee, and the only thing she said was “are u drinking enough water” I’ve been drinking plenty of water I’ve always drink a lot of water and now I drink even more because of the pain.
