i had my little one when i was 38,,, she was an easy, healthy pregnancy... I begged my husband for another one at 40....he was dead set against it... I am now going to be 43, and i can't even imagine being preggo again and starting over...I wouldn't want to put my or the babies health in danger....
His family has a history of downs syndrome so that played an important part in the pregnancy even at 38 yrs of age...
I can't answer for you mama, but i can tell you even though i yearn to be pregnant when i see bulging tummies, i know it was the right decision to stop for us...
best wishes to you and your family.
