I'm 39 and have PCOS, regular normal periods for a few years. Current period has been normal flow for the last 3 weeks? :(

I need to go and see the Doctor next week as wishing the period will just stop/go away isn't helping .

Have you any helpful advice as to what this might be?

I once had a period that lasted 25 days. I had a coil at the time, the doctor whipped it out and said the bleeding would stop in a couple of days, which it did.

At the time I was perimenopausal.

Thank you for answering Pixel.

I hope to see the Dr or nurse on Tuesday.

I will update. :)
