[|Human|] How worried should I be about the possibility of getting pregnant at age 48 from one night of unprotected sex with my husband - one week after the first day of my last menstrual cycle?  Had my son at age 44 -conceived naturally after 4 years of unprotected sex.
[|AI|]  Hi, How are you doing ? From worldwide studies & my personal experience I feel you need not be worried at all. 45 yrs is age of the eldest mother in world. But miracles do occur. But in your case another factor going against chances of pregnancy is the day of periods. Ovulation occurs around Day13-15 of the period. Day 1 being firs day of bleeding. Life of egg is only 24 hrs & life of sperm is only 3 days. So there is no chance a sperm would have survived from Day7 till Day 13. All these facts put together Pregnancy chances is nearly Zero Hope I have clarified your overall the best Chat Doctor.
