Vomiting after taking a contraceptive pill

Patient: Hi. I’m taking oral contraceptives. One day, I vomit within an hour after taking my pill. I just ignored it and take the next pill the next day and so on. I also have sex with my partner 2 days after I vomit. Is there a high possibility that I could get pregnant? I am taking a 21-day pills. Thank you.
