Hi Birdy,
Happy to hear you’re in NZ. I’m a semi permanent resident (live on the Coromandel half of the year).
Regarding utrogestan which I take continuously, 100mg orally makes me (and many others), feel really really desperately low, but increasing the dose to 200mg orally has the opposite effect. Have you tried taking 200mg? I’m told by my specialist here in the UK that the low mood is your bodies way of screaming for more. It’s odd that when oestrogen doesn’t fix something or makes it worse, we immediately think we need more, but we don’t apply the same thinking to progesterone.
Anyway, you could try a higher dose and see how you feel.
