Have you taken an HPT yet? I would say because your body is going through the change, then it might be possible for an egg to have slipped out. I'm not really sure. Try a pregnancy test and see from there. If you really truely think you might be pregnant, and if the test is negative wait a week re-do the test and then make an appointment with your doctor. Pregnancy symptoms and PMS symtpoms and menopause symtpoms can all mimic one another.
Hello, from your age and has been for so long without menstrual , you may be relatively small chance of pregnancy. But on the other hand the human body is a complex system, anything can happen, so do not rule out the possibility of pregnancy. I suggest you go to the hospital in time to do some checking, because women after menopause to reduce estrogen makes the body some changes.
