Dull pain after ectopic surgery

I had ectopic surgery with right tube removal in November 2018. I have had 2 cycles since the surgery, each 45 days.

Randomly throughout the cycle I get dull, achy cramps on my right side, pelvic area. I know the normal reasons for cramping like ovulation and af, but today I have cramping that I don’t believe is related to anything since I’m cd17/45.

Are there other things you’ve noticed causing pain post surgery? Mine was laparoscopic and recovery went well.
