It basically means getting pregnant after 35, when society thinks you should be retired but instead you are changing diapers at 3 AM! It's tiring, but totally worth it.
Doctors call it advanced maternal age when you are 35 or older. My gynac told me that while there are more tests involved, most women go on to have perfectly healthy babies.
It is technically pregnancy after 35, which requires a bit more monitoring. My doctor at the private clinic explained all the extra screening tests very clearly, so don't worry.
No matter what age you get pregnant, those midnight cravings for ice cream are exactly the same! Late pregnancy just means more reasons to pamper yourself with good food.
