Progesterone levels concerning helllp

Steph

In August I miscarried I was out on progesterone to support pregnancy baby implanted well and even had a heart beat! But sadly lost baby

Roll forward I’m 4 weeks today hcg 23 ✔️ progesterone is 20n/mol so on the low side, I’ve been put on progesterone again.

He said 20 is lower side but not too concerning however we can’t rule out ectopic! I’m shitting myself because I only have one tube from a previous ectopic :/

Can people tell me there progesterone numbers in there first few weeks of pregnancy. I believe most countries measure in ng/mol if not it’s it in ML
