I had my first 3 kids at ages 28, 31 & 34. Then I had 4 miscarriages, the first at age 37 & then 3 in 13 months when I was 41/42. So I could get pregnant easily but keeping it was the problem. Of course, I have a uterine abnormality (incomplete uterine septum & heart-shaped uterus), so I’m lucky I was able to carry my first 3 babies to term in the first place!
I’m very sorry about your losses.
