I am pregnant, 7 weeks, I have terrible nausea, vomitting at least 1 x daily, exhaustion with any movement, I have felt like thing for one week. I will see dr in the next week and my mom is here caring for me, making me eat and drink which has been good and I feel a little better. My question is for thanksgiving we are going to have a two hour flight and I was wondering it if was safe for me to do this ?
