Birth Control and Vomiting????

I literally just began my first pack of my first ever birth control (Mono-Linyah) yesterday evening. I took it with my over the counter iron supplement for my anemia. I took it with food, as well. This was at 9 pm. This morning at 4:30, I woke up nauseous and got sick. Could this be related to the medication?! I'm not one to get sick so I'm just paranoid about it lol
