Me and my boyfriend had sex on sunday 11-8-15, and the condom ripped. So we ran to cvs to get plan b and i took it when we got home. And i ate like 5mins after taking it. I saw that greasy food may affect it. I ate 10 pieces of hot wings and a medium size fries. Is there a possibility that i might be pregnant still? Yesterday 11-17-15 i felt weird. I didn't eat at all and every time i would try to eat i felt like throwing up and i was very tired. I want to know if that is normal or if i should be concerned?
