well i would say if it is the begining of menapause it could be possible. But to be sure check with your doctor or take a pg test to be sure.
My grandmother got pregnant with my mom during change of life and my aunt got pregnant with my cousin during change of life too, so it is possible. Both of them were going through it early though, only 39.

Yes. Depending on how old you are, it is not that likely, but it is medically possible even if you have not seen a period lately. The period does not start the process and cause ovulation, instead the period follows ovulation, so if you ovulated and then got pregnant, you would not see a period.
