Please help. Should I be worried?

Im 24 and I had a D&C 2 weeks ago for my MMC. This was my first pregnancy I was 15 weeks. I hemorrhaged during the surgery and my Dr said that the normal 20 min procedure ended up being 1hr and 30 minutes long. She told me at my follow up that it was a very intense and aggressive. I am having cramping and sudden intense sharp pain randomly. I’m so worried that my uterus will be damaged and I feel like my Dr doesn’t listen to my concerns. What do you think? Am I just overthinking everything :/
