assessment of fertility
I can understand your concern for baby but as you said chances of pregnancy
decreases as the age advances. At the age of 45 you might still be fertile but to know that I would suggest you to get an ultrasound
for assessment of antral follicle
count and some hormone assays especially FSH and AMH; and then consult your gynecologist. Don't take any medicine without proper assessment as this will be a waste of money and effort. In case you don't have good fertility potential then you can opt for donor egg IVF (In vitro fertilization
) after preparing your uterus to accept the same.
Take care and all the best.
