I had my 21days pill (BC) nd me & my bf had sex nd came inside me. Now i got my period but its four times lighter than my usual period. I got 3days of my period only. Is this a sign of preggy? Or effect birth control (This was my first periodafter taking)

By the way i vommit early in the morning but i was drunk last night but i only had saliva. Additional question does emergency pills makes you vommit? Because the day before my period we had sex and came inside me so just wanna clarify something if this is normal? Or not.
