Progressive right lower pelvic pain that radiates to my side. Worsens upon moving???

Ladies: for the past couple of weeks I’ve been feeling what almost feel like just pressure down in my pelvic area, only on the right side. During certain sexual positions, the pain is almost too much to bear. Now, it feels as if it’s progressively gotten worse to where it hurts now if I move or bend at the waist, or even sitting down, like anything that’ll put pressure on that area causes it to hurt. I’ve had dysmenorrhea this month, which isn’t totally abnormal considering when I was on the pill I had irregular periods anyways. I’ve taken 3 pregnancy tests all of which have been negative.

Any ideas on what this could be? I’m trying to avoid an ER visit, and my GYNO can’t see me for 2 more months.
