Hello, Thanks for letting us know your health concern. I have gone through your query and would like to offer you some information. Considering your age, you can presume the current situation as peri-menopause. It is very very rare to conceive at this age, especially when permanent sterilization took place. The ideal way to deal is to have a proper clinical exam, pap smear, hormone assay and a sonogram of the pelvis preferably in the trans-vaginal route. If everything is fine, induction of the period can be done if needed. Hope this helps.
