zofran safe for my baby?

Hez

ive been terribly sick lately. im 8w4d. my doctor perscribed me zofran today. i read about it but omg, im totally freaked out. it says it is not fda approved and has been known to cause birth defects such as cleft lip and heart defects. have any moms had a heathly baby and were perscribed zofran? i havent been able to go to work for 3 days and i am hoping for relief. but i do NOT want to risk the health of my baby. ive tried everything...
