I've just been feeling nauses to my stomach for a week... and I've never been pregnant before so I took two home pregnancy test snd both were negative yet I still believe that I am. I just feel I need some professional advice

We really can't tell you if you're pregnant, no one can.

Your title says "if you eat something that the baby doesn't like will you throw it back up?" The answer is no. Morning sickness has nothing to do with the baby not liking the food you're eating.

If you really feel that you are pregnant, wait another week and try another pregnancy test. How late are you? It may have been to soon to test. Also, did you use first morning urine when you tested? Urine first thing in the morning is more concentrated and therefore more accurate.

Good luck. I hope it works out the way you want. :)

The baby, if there is one, won't object to anything you eat. That wouldn't be why a pregnant woman throws up. She throws up because of hormone changes.

In your case, it's much too early to tell if you are pregnant. Meanwhile, abstain from smoking and from drinking alcohol, and take prenatal vitamins while eating a good variety of meats, fruits, and vegetables.
