Hi, I have not taken my marvelon 28 for a few days, and decide to wait the following week, to start fresh, instead of taking 3-4 at a time. (a doctor told me that once)I had sex relation this past saturday, and only started to take my marvelon back on sunday. any chance i could be pregnant. actually had nausea last night, but i'm thinking a made a food reaction. please advise. thank you (I am 23 years old female with no medical history)
