I'm 32 weeks and unfortunately I still have morning sickness. My doctor has prescribed Zofran tablets and phenergran suppositories to help me take in some nutrients. Hopefully you won't feel this way add long as me but early on its not unusual. Talk to your Ob about an anti emetic.
I did that from week 9 to 15 weeks and had some morning sickness till I was 25 weeks. I am now 28 weeks tomorrow. Try licking some salt and drinking some Gatorade it does help settle the stomach so you can eat and keep food down.
It's common. I'm 23 week and still get that though doctors advice should always be sort in such situations
