Looking for Advice—HCG & Progesterone Concerns

I’ve been tracking my HCG and progesterone levels, but my numbers aren’t rising as expected. I had a sonogram yesterday, and there was a heartbeat, but I’m worried about why my levels aren’t increasing properly.

Here are my results:

• 2/12: HCG 122 / Progesterone 37.7

• 2/14: HCG 262 / Progesterone 31.1

• 2/20: HCG 3,092 / Progesterone 37.4

• 2/27: HCG 7,489 / Progesterone 23.7

• 3/7: HCG 14,025 / Progesterone 18.9

I’m really anxious and don’t know who to ask. Has anyone experienced this? Any insight would be greatly appreciated!
