to determine the number of eggs remaining in my womb cause i have only
one child 14years ago i still want more...

So long as you see your monthly flow you should still be able to have children.

If you still want to have more kids....see a gynecologist at a teaching hospital to discuss options like IVF.

No monthly flow again

If you no longer have monthly flow then you may have reached menopause. The age at which menstruation ceases depends largely on the age you started menstruating. If you started very early, say nine to eleven, then there's a high chance it will cease before you hit the age of 50. You should go for check up in a hospital to know if you have reached menopause. Some illnesses or diseases can cause menses to cease, but that can be reversed using proper medication. If you have naturally reached menopause, then naturally you will not be able to conceive. However artificial means of conception may be an option in this case, using an egg from a donor.
