I didn't actually start throwing up tell about 10 weeks so they don't think mines ganna go away tell 20 weeks. Everyone is diffrent. I'm on three diffrent kinds of meds now so I can eat. If it gets to be to much call your doctor.
In my first trimester I was extremely nauseous as well what really helped me is the preggie drops their sour candies you can buy online or at a maternity store and they really helped me with the nasuea or lemon in water. The nasuea and vomiting usually goes away when you begin your second trimester I was even worried that something was wrong because I felt so great in my second trimester lol good luck :)
They say it will go away at your second trimester. I will be 13 weeks Saturday and I have had it rough with morning sickness for several weeks. To the point I didn't want to leave the house bc I got sick so much. For me I feel like its getting better but I do have good days and bad ones. My doctor prescribed me some meds that are safe for the baby and help with nausea. Everyone is different so im hoping it goes away for you soon. Ask your doctor about nausea meds.
