PLZ comment- flying pregnant

momma • Angel mama to my son 💗 earth mama to my daughter
I'm 12 weeks today and taking a 4 hour flight on Wednesday. I have a few questions, should i opt for a pat down or is the scanner definitely safe? also, i always get really bad motion sickness when i fly, ever since prepregnancy. It makes me puke my entire flight every time): I have some zofran my dr prescribed but havent taken it due to hearing bad things about it. Should i take it before i get on the plane or stick it out and puke? thanks in advance
