Zofran while pregnant

Hello all! Just need some advice. I am 8 weeks pregnant, almost 9 and my nausea is crazy. I have 2 girls, 5 and 4 and I have never had nausea before. So I went to the doctor today and they provided me with zofran, 4mg that dissolves on your tounge. I have read some good and bad things about it and want to know if anyone else has taken it with healthy babies! Please let me know :) thank you!!
