1st Baby

Two days ago we found out we were expecting our first. The pregnancy was confirmed at the doctor however my hcg levels were only at 30. We went back today hoping for an increased number only to hear my numbers were now at a 13. I'm confused and hurting and wondering how to handle this appropriately. I don't want to lose this precious gift from God. I am going back Monday and praying for a miracle to happen. If not, we will continue to try.
