Am I prego

Dallas • I don't give no fucks, like a virgin hoe that won't fuck
Two days ago my boyfriend came over and we did it on the couch, while having sex I was somewhat pulling him in closer ... So at this point he's about to ejactulate and he waits to the VERY last minute to pull out 😐 should I be worried ... Some got on my hand and what not but I'm afraid some got in my vagina .. So this man God bless his soul .Starts trying to scrap what could've been him out of my vagina 
Should I wait until two weeks to take a pregnancy test ?
Should I take a EC? Today would be the third day ...
In additional canyou become pregnant from sperm on the vagina ? Like on the lips
