Hi Niamh,
I use mirena coil and oestrogel, I'm 51 and menopausal. I started using one pump oestrogel for first 5 weeks, then upped it to two a week ago, as I was still getting hot flushes on waking.
I have had four days this week where my mood has been awful, I've felt withdrawn and snappy, I too have been wondering if the extra oestrogen has caused this, but think I might give it a while before I decide if it is the case.
I know we are using HRT for different reasons, but I too wonder if too much oestrogen has an effect in mood.
The other thing that I have debated is, I do the 5:2 diet, and I think if my blood sugar drops too low, it effects my mood also.
