Left pelvic pressure

I constantly have left pelvic pressure. Sometimes during intercourse. It’s been on going to a few years now. I’ve gone to different doctors multiple times and they have all said there is nothing wrong. My cycles are 31 days long, I’m super regular, and I don’t have painful periods. I do cramp, but it’s bearable. Anyone else experience this? I’m tired of being told I’m fine and nothing is wrong when the pressure is constantly there. Sometimes daily.
