Extreme Abdominal Pain...6dpo

Last night me and DH BD’d. I was fine during and in the shower afterwards. Then while I tried to urinate, I got EXTREME pain in my uterus/abdomen area. It stuck around and hurt so bad I was laying on my floor crying. I had back pain, abdominal pain and extreme nausea. This is our first cycle after our MMC at 11 weeks. I contemplated going to the doctor but the symptoms seem to be going away today slowly. Has this happened to anyone else? Normal? Not normal? Should I go to the doctor or no?
