I need some comfort please

Ana

So I had no trouble conceiving my first took me about 2-3 months after him , i had gotten pregnant again but took me 8 months i had a misscairage early at 10 weeks no fetal pole or yolk then I got pregnant a month after that and had another miscarriage as well I got to see baby this time but had no heartbeat lost baby at 5 weeks , i have no medical concerns that I know of . I’m 21 years old healthy we want our little bundle of joy so bad my son is already 3 years old so I think it’ll be a perfect age gap . What can I do to avoid another miscarriage and get pregnant faster of course only god can help . I pray and been asking for a miracle badly
