What are the chances of a 48 year old having a baby?
My mum’s boss had her first baby at 53 without IVF. Some women don’t hit the menopause until a late age, so 48 is plausible! It is no secret that the risk of miscarriage is a lot higher for a 48 year old, as is the risk of downs syndrome. However like everyone else once you pass the 14 week stage your miscarriage risk is reduced and all you can do is take the best care of yourself and maybe finish work early. An amniocentesis test will warn of any birth defects. However women of certain religions choose not to as it is invasive and the outcome does not matter to them any way. Good luck to your mum if she is pregnant.
