I need to relax, I been so anxious.

I have had 2 miscarriages, 1 in July and another in October! I am 15 DPO, and my test are positive but i just can’t stop thinking of another miscarriage. I had my blood work done on Monday when I was 12 DPO and my levels we are 78.. I feel like that’s super low and get discouraged when I see other hcg levels. I being so hard on myself and taking away my own hope because I can’t stop thinking about it. I called my primary and asked for a second blood draw to see if my levels have doubled. I am waiting on a call back. I’m just praying 🥹
