Hi msoctober63 & Welcome
I think we need a little more info about you for us to be able to comment on your questions. You've been given the mini pill not HRT - what age are you? Are your periods erratic because you are peri menopausal? Are you getting any other menopausal symptoms?
Micronor is a contraceptive pill with the progesterone Norethisterone. I don't know if or why it should be prescribed for erratic periods if you are peri-menopausal!!!!! It may have the effect of stopping or reducing your periods but most of us on this site will be in peri or post meno and will be using HRT.
I have to say, that if you are peri meno then Micronor would be a strange thing to prescribe - I would have thought a Mirena coil with a bit of oestrogen would have been more appropriate!
Do give us some more details so we can advice accordingly.
