Overcome Menopause Changes and Risk

Is There Any Risk Of Pregnancy During The Menopause?

I’m 49 and for the first time, I haven’t had my period for three months. For the last couple of years, it’s been very irregular, i e, it could come after two months or so, sometimes light and sometimes very heavily. As it seems to be over now, or so I think it is, should I still be careful to avoid the risk of pregnancy?
