Can i get pregnant after i get my period weeks later because its been two weeks since i got my period and now i throw up everything i eat or drink?

Possible but unlikel: In either event you should get a pregnancy test.

Yes, but too soon: Yes, a woman can get pregnant 2 weeks after the start of her last period. That is when many women ovulate. However, if she just conceived, she would have no symptoms from that conception (it is too soon to have pregnancy symptoms). More likely, vomiting would be from other causes, such as a stomach virus, the seasonal flu, food-related causes, etc... One's primary doctor can help, if needed.
