Well, you have two options, either throw up now and not worry about it later (this relieves pain too), otherwise, just drink something and have something to eat. Don't try anything too sugary like one of those Starbucks unicorn drinks (I don't know if they still exist but hey, just a warning!). Try a soda or just plain water. For something to eat, try a corndog or something that you like. Most people like pizza, so try a nice greasy pizza!
That is incorrect. A woman does not hit her birth giving prime until her early to mid twenties. A teen is at high risk of miscarriage, pre-mature birth. The baby could suffer with low blood pressure and anemia.
