Getting pregnant after 45

Ains

Has any of us ladies in here conceived after 45? With successful pregnancy and healthy bub... I'm being told at 48 my chances are slim with higher risk of % in down syndrome etc. I've seen ppl having bubs after 45 and they've had no issues... also being told I could conceive without ovulating? Being sent off for bloods and ultrasound... anyone else going thru or gone thru this?
