Zofran?? Morning sickness?!

Shelby • We has a Peanut! #Blessed
I am 8 weeks pregnant with my 2nd child. I have morning sickness pretty bad that seems to last all day. And the only thing that seems to work is Zofran. How many of you guys have taken nausea medication? I just read a couple articles that say there may be harmful side effects to the baby taking Zofran which scares me.... Any ideas? Or comments?
