Progesterone Scare

I did some bloodwork yesterday to compare my progesterone levels from last week. I got a call today from my doctor's office that my levels have dropped a little from 21 to 17. So the doctor wanted to put me on progesterone to prevent miscarriage. I will have to take it everynight until the doctor thinks I am good to go. They think I will need to take it for 12 weeks. I pray to the Lord that everything will work out. I already love the little bean in me. I know it will work because it is in God's plan.
