Zofran

Is zofran ok to take while pregnant it doesnt say it harms the baby. What are your thoughts? Experiences? Im almost 12 weeks Im debating if I should start the medication or not im just afraid of needing it every single day 6 months is a long time I know nausea doesn’t last long im hoping it doesnt I just been fighting it off. It keeps coming back I was fine after having severe nausea a couple of days ago and its starting again everything I eat. Hoping liquids stay down but Im afraid if I start zofran that I might need it all the time?
