Everytime i eat i feel like i wanna throw up, & i'm peeing alot more. could i be pregnant?

Pregnant : It's possible you could be pregnant. Are you sexually active, do you use protection, do you have more than one partner, have you had a delay in your period. Another reason for increased frequency of urination is a potential urinary tract infection. I suggest you take a pregnancy test and get screened by checking your urine for any bacterial source.
