Hi Midlifecrises72!
I started 10 months ago on 100mg Utrogestan (continuous, as no period 2+years).
Because of bleeding, I was upped to 200mg daily just over a month ago.
It's got overall benefits with some downsides: sleepy at night is ok but grumpy mornings not so great!! I'm sticking with it for 3 months, hoping that the low mood improves. I had terrible migraines all my 'hormonal' life & HRT stopped them overnight so that alone is worth the not so great effects for me!
I personally would give it 3 months to see it it settles.
Good luck
