Progesterone levels

Hi,
I am 7 weeks and 3 days pregnant. 2 Days ago I started spotting (only on toilet paper). The spotting stopped the next day and I went to the dr and my hcg was 59,000 and progesterone was 18. The dr said it was good but I am worried because two weeks go my progesterone was 23 and two days before that it was 26. I did an ultrasound at 6 weeks and all was normal. They just put me on progesteron suppositores. I had 2 miscarriages in the past and am very nervous. My next ultrasound is in 6 days!!! I just wanted to get your input on what you think about my progesterone dropping and if the suppositories can fix that problem at this point. I am realy nervous.

I think that's the whole point of the progesterone suppositories, is to help when your body doesn't create enough of it's own, naturally.
