Progesterone Supplement?

So, I had my first appointment on Friday and based on my last period, they figured I was probably 9 weeks pregnant, but I have very irregular cycles, so they did an ultrasound to check. Well, low and behold, they told me all they could see was a gestational sac and that they thought I might be five weeks or earlier. (That does make sense because my basal temp only rose more recently.)

My doctor also said she would check my progesterone levels and if they were low, prescribe a supplement.

The nurse just called and said everything looks good, except my progesterone is a tiny bit low. So, they called in the progesterone supplement for me. I’ve hear conflicting things about what that means? Does anyone have any positive stories that started the same way?

I go for another ultrasound next week.
