Nausea on utrogestan ?

[Vintageroses]

I’m having an awful taste in my mouth and nausea nearly everyday and I’m not sure what’s causing it. I’m thinking it’s either acid reflux ( I do have a long history of this and take lansoprazole which doesn’t always work) or it’s the utrogestan that I’ve now been taking continuously for about 3 months.
if it’s the utrogestan would I likely have the same problem with other options like the mirena etc ?
has anyone else had this problem ?
I also have terrible pms like symptoms that seem to go away for 1 week out of every month and I have no idea if this means I need more oestrogen , less ? I’m fed up with it all now.

I had the same. Constant nausea on my progesterone days. Also had low mood and no energy and my relatively regular cycle disappeared. It was awful. I tried multiple times to get a GP appointment and couldn't. I've come off it and feel so much better. And peri symptoms have not yet returned.
