Progesterone Drop again…

I had a twin miscarriage in July, we went to our ultrasound & there was no baby in the sac. Progesterone levels dropping were the first indicator that something wasn’t right so we started supplements, but hcg was still doubling. Had bloodwork & ultrasounds every week for 5 weeks to make sure we just didn’t have wrong dates before doc prescribed misoprostol.

Now I am pregnant again, 4 weeks 5 days today. My hcg was 305 progesterone 16.7 on Tuesday, hcg 648 & progesterone 13.3 on Thursday.. has anyone had any positive outcomes or should I start preparing myself for the worst again..
