Cigarette smoke is something that's a warning sign of a migraine for me. You may be more prone to those on progesterone

Hi!

I found this thread which seems related and a number of other threads and results, so it looks somewhat common. Perhaps you could talk to your GP about it?

Are you taking your prog orally? If so, you might not experience that symptom if you were to take your prog some other way, such as anally, through your skin, or through an injection. Oral prog gets broken down into a number of different substances and can have strange side effects whereas other routes mostly avoid this.

A smell like cigarette smoking?

The folks I've known on Progesterone, they tended to smell things like baked goods. Honestly they smelled like baked goods. Something akin to sugar cookies, maybe with hints of vanilla and butter.

I know that some people report a more musky smell, again usually coming from themselves, and that's caused by fluctuations after starting progesterone, and levels out after a dose or three.

There's also some reports from menopausal women that take it where their sense of smell gets heightened.

I don't know if that helps or not, but other than the smell you're noticing being unusual for what I've noticed in person, or read about, it is a fairly common occurrence. Enough so that I've looked into it for fridges friends, and saw the stuff about menopausal women, and some talk about testosterone spiking for a bit after starting progesterone.

It's not first person experience though, so I dunno if that's useful to you or not.
