Is this menopause?

Hi. I am 51 years old and recently came off the pill, Cerelle. Now 3 weeks later my breasts have been extremely sensitive. This has been going on for a week now. I haven’t had proper periods in years but nurse said (last year) it might also be because of Cerelle.

I have read that this sort of symptoms might be the beginning of menopause.

Has anyone else felt like this?

Thank you in advance.
