Periods changing now in my 40s?

Hi all,
So I’ve turned 43 and these last two cycles my periods have almost been non existant. I’m going to discuss with Dr too but I’ve recently had an ultrasound of whole pelvic area and that was clear and my last Pap smear was fine – two years ago.
I’m getting period pains as such but only the very starting of my period and then nothing. Anyone else experienced this as age and hormonal changes set in? I just feel I’m too young…. share with me your bleeding or non bleeding stories in your 40s! Thank you.
