Could even be pmt, I used to get like 5 days before my periods, they actually put me on Diazapam 5 days a month as I was over the top anxious & in the surgery in floods of tears.
If it is peri menopause I hope you have a good doctor, at my surgery I have just been told today that I need to manage it myself because I am just peri menopausal, it wont be until 47,48 that they would start thinking about hormones, & I have a lot of different symptoms, including very irregular periods now. I'm 43.
One thing I don't get so much of at the moment is hot flushes. I think she did mention I would need to be having bad ones of those. So you may find they listen to you.
