Hcg level

Hey ladies I need some support, trying so hard to stay positive, I’m currently 4wks 6 days. I had my levels check here’s the break down

3/3 84

3/5 122

3/9 406

Dr called with those last results, I go back Wednesday for levels and have a ultrasound Friday to make sure I don’t have an abnormal pregnancy. I’ve experienced 5 miscarriages, I’m trying my hardest to be strong and positive but it’s so hard. My husband is so supportive but it stressful for him as well. Should I be worried, also I’m taking progesterone, lovenox, baby asprin. So this journey has been so intense, I just want my rainbow.
