Im 19 about 5'4 and 125 pounds. I have recently been getting nausea out of no where and then throwing up. Today i just ate a Chocolate candy bar and not even an hour later i had to stop the car and that was the only thing i had ate so far. My hands have been getting kinda shaky lately also. Everytime i eat i feel like im gonna throw up but i dont always actually throw up just sometimes. Could i be pregnant? My last period was may 27th-June 2nd i have been trying to conceive
