Hi I am 40 years old I have one son he is 15 years my husband was not with me for 9 years so I couldn't try for another baby I have seen my family doctor here he has given me Preg Vit and Metphormin. I am concerned too. I really pray I get one but if it's not in my luck what to do.
Woman age 40 and above can also conceive as long as they are ovulating and have regular cycles so don't get disheartened. Continue the medicines prescribed by your doctor but I would suggest get your hormones tested , FSh, LH, prolactin, AMH on your cycle day 2. These tests will help know the ovarian reserve and your chances to conceive naturally at your age.
Wishing you all the best.
St 40 preg is difficult some times do immediately see a good gynaecologist
