So I have a lot of things going on

So I’m pregnant I’m pretty sure not that far along but I keep having bleeding and some small clots but I got to see my sac yesterday and my hcg levels are increasing but not how there supposed for a normal pregnancy but they’re increasing . I’m always worried because of the bleeding idk what to do... there’s not I can do but pray and hope for my baby my doctor said it was good news yesterday that we saw a sac in my uterus and I am so happy but the bleeding is making me worry now 😭 I keep having blood so I get my hcg checked and they keep rising , any tips or anything from moms has anyone experienced this before ???
