Low progestrone at 7 weeks

Natasha

I am currently 7 weeks pregnant and my hcg levels last week were in the 6,000 and my progestrone was low at a 7 and this week it went up to 30,000 but my progestrone went down to a 5 and I am on oral progestrone 200mg once a day. Has anyone ever had this or should I be worried? The doctor is doing a sonogram tomorrow and didn’t seem concerned
