I need somebody to talk

Do you have to have a D&C at 5 weeks ? I had miscarriage at 5 weeks June 1st but became pregnant 4 weeks after. I’m having another miscarriage. I know this is going to mess up my fertility since I’ve been pregnant 4 time but only had 1 successful pregnancy. My heart hurts so much since I’m so young . I’m confused and scared with my body and doctors don’t do anything but sugar coat EVERYTHING . I’m done trying to have another baby . Maybe god only wanted me to have one kid .
