I am 56, 6 years into menopause, and getting ready to enter into an intimate relationship. I am also on bioidentical hormones. Can I still get pregnant? I recently had a scare, felt some symtoms of pregnancy, so I did take a test, of course, I was not. Whew...but for future reference, I need to be safe. And I am allergic to condoms, and cannot take birth control. Will I be safe?
