If I’m concerned about DHT conversion, how long after getting on Dutasteride should I wait to resume taking Progesterone?

Previously when taking Prog I was able to confirm with bloodwork that it was raising my DHT. It wasn’t a ton (< 3ng/dl off Prog vs 8ng/dl on), but any conversion was enough to scare me into either quitting Prog altogether or trying to block the conversion. Since I’ve heard Dutasteride should be sufficient for fully blocking that 5-AR conversion I’ve just started taking Avodart this morning, but I know that Dutasteride also takes a while to build in the system before it’s fully effective.

So my question here is how long should I take it before I can safely reintroduce Progesterone without worry of that conversion?
