nuva ring waiting time

2 saturdays ago i inserted the nuva ring but that night my boyfriend and i had unprotected intercourse actually twice that night. We didn't use anything thing else to protect us. He went in me (a better way to say it) not reading that the suggested time to have sex is 7 days after inserting the ring. i'm currently nauseated, i feel all the acid in my stomach when i lay down,and i'm extremely sleepy all the time. Could there be a possibility that i'm actually pregnant? I keep looking on the net to see if there could be a possibility but i haven't found any answers yet. any advice i'd love to hear it. thank you!!
