Muscle cramps ovary area

Nomi

I’m 12 weeks pregnant and I have been experiencing muscle cramp/tightness in my very low abdomen area. Where my ovaries are. It normally happens when I try and get up or roll over. I mentioned it to my OB and he didn’t seem worried. He said it could be round ligament pain or from scar tissue from my past C-section. But it’s worrying me because it happens every single day! I just laid in bed and tried to roll over and it feels like my ovary or a muscle right over it just tightens up and causes pain. I have to lay flat and massage the are to loosen it. Has anyone else ever experienced this? Any tips??
