Help! Am I starting the menopause?

[GW2]

I am nearly 46 and for the last year my regular 28 day cycle has gradually become 21 days. I have now been feeling PMT, swollen breasts, bloating and abdominal twinges for the last 2 weeks, but no blood. Was worried I might be pregnant, but did a negative test today. So now I am confused. I thought the menopause meant you didn't have a period at all, I didn't expect to feel like my period was imminent for a couple of weeks or more! Has anyone else had this experience?

PMT but no bleeding is par for the course! Very common.

I'm nearly 48,and I get missing periods,as well as double periods and longer periods,allbeit,these things happen once every 6 months or so.
I also have started getting bad indegestion and forgetting even simple things.

I wish it would bloody well hurry up...I have no need for periods as my shop is well and truly shut.
