Anxiety with new pregnancy after miscarriage

My due date was May 1st 2020, we miscarried at 16wks1day to what doctors say were due to short cervix (they’re putting in a cerclage sooner this time around).

I’m 5 weeks today and I can’t help but be anxious and feel guilty. I love my baby and I feel blessed but I’m weary. HCG levels nearly tripled. Just had another HCG today...Please let me know I’m not alone and tell me your success stories with rainbow babies 🌈 💕
