Is it true?

I have an aunt who had a a few miscarriages and wouldn't be able to have the baby's. She would have D&Cs a lot & her uterus stopped working so they removed it. I had a miscarriage in April & had a chemical pregnancy this month. I'm scared if I keep trying I won't be able to have kids a lot & the same thing would happen to me. But at the same time I want to keep trying because I could be able to have kids.
