Scared I can't have children 😔

Hey guys. I am 21 years old and have had two miscarriages. I also have sickle cell disease (a blood disorder in which my red blood cell aren't circular , their curved, causing them to get clotted and cause pain). I know a lot of people with sickle cell who have succeeded in having children but I've heard that we can't carry children. I'm just scared that May be one who can't carry. I know I'm only 21 and have a lot to accomplish before I think about kids, but I lost 2 of my babies and it bothers me. I just need some reassurance.
