Vibration sensation In the Uterus and ovary?

Ok this might seem weird but ever since ive started with the fertility treatments (3+ years ago) I keep on getting this weird vibrations on the right part of my uterus and ovary mainly but sometimes also on the left part. It feels like the constant twitch in your eye that we all sometimes get.. ive noticed that i get the feeling few days after ovulation till the end of my cycle... I've spoken to my doctor about it and she just smiled and said its probably just gas. I know what gas is like and im 100% sure that this is not gas at all. Its because for her that i feel embarred to ask someone else. I've been trying to get pregnant for the past 3+ years but never achieved a pregnancy even though I went through 4 IUI and 2 IVF+ICSI+PGD.. I dont know if this vibration sensation could be related to it in anyway.. I dont have a uterine fibroid but i was diagnosed with very early stage of endometrioses and scar tissues were surgically removed.
