I had some
heartburn with DS into the third trimester
and I heard that meant a full head of
hair on the baby.....and DS was born a baldy, LOL. He didn't even need a haircut until he was 18 months old!
I've had more heartburn this time and earlier on, it started in the second trimester. I don't know what we're having....but I"m pretty sure that heartburn, like many other pregnancy symptoms, doesn't indicate one gender over the other.
