Should I go to ER? Extreme pain

I had my period earlier this month and it was fine. I woke up this morning, in extreme pain and distress. I’m talking rolling around screaming in my head. The pain is in the center and right at the bottom. It spreads over to the right or left but consist with the bottom part of my stomach. There isn’t even blood coming out right now. My mom had fibroids. I don’t know if I should go to ER. If that will do anything. I have an endocrinologist appointment but it’s in August. I just have a feeling that this isn’t ok.
