Something is wrong with bladder.

this is ridiculous, my bladder hurts all day long, after I pee in the morning it hurts the rest of the day, I’ll try to drink bottles of water and nothing, sometimes it helps but once I pee again it’ll hurt again. I can’t explain if it’s burning or just uncomfortable, all I know is it hurts. Sometimes once it stops It gets late at night and I’ll notice it starts back hurting. I find myself pouring water down there before and after I pee to try to ease the pain. I’ve always had this problem when I was younger maybe around 9 but it was never this irritating to where I noticed this bad until December after my first prenatal appointment which it’s worsened the past 2weeks, I’m 17weeks pregnant now. I’ve told my ob, they’ve tested my blood work for herpes, syphilis, hiv/aids, hepatitis etc, Urine for uti, swabs with Pap smear for yeast, bv, and sexually transmitted infections. NOTHING for every single test. It’s gotten to the point where I told them to retest me just in case the test weren’t accurate, because I find it so hard to believe them. It’s just I’m worried that something is probably undetected, I don’t wanna hurt or loose my baby :( so irritated , has this happened to anyone to where it was nothing wrong? I’m really thinking painful bladder syndrome or internal cystitis. Idk I’m worried for my baby not necessarily me. Maybe I need to see a urologist? Many might say it’s my baby on my bladder but honestly I don’t think so it’s literally hurting so bad 😞
