I'm 49 and have peri menopause symptoms. I've been checked out and my Dr has agreed to prescribe HRT. She said it's normal for a woman who still has her womb to use progesterone too with oestrogen and has advised I have a Mirena coil fitted before starting oestrogen patches. I hadn't come across this before - anyone else? I've never had a coil before so a bit anxious about it...thanks!
