Bladder issues after vaginal birth?!? Help!

Okay so I had a baby 16 months ago. And a few months ago I had an onset of uti like symptoms. I went to the doctor multiple times but my urine was clean. So now here I am again and the problem is getting worse again. I am having way frequent urination, like 2x the normal amount, I constantly go to the bathroom as I feel like my bladder doesn't fully empty and extreme vaginal pressure, sometimes cramping. But after doing some research online I read about bladder prolapse and how it could show up later on. I was waiting to see a specialist because I thought my diet was contributing to this problem as I am a religious coffee drinker. So I'm not sure which it is. But I don't think I can deal with this issue anymore especially if we are TTC.
