Okay so I have been on pills before but I stopped for a couple months and my gyno put me on orth tri cycling because it's better with younger girls. My pharmacy gave me the generic version which is tri sprintec(not sure if that matters). My boyfriend and I had a lot of sex without condoms this month. And then on the third to last day of my active pills I forgot it so I took 2 the next day. I got sick or nauseated or something and was throwing up the whole day. So I had 1 pill left the next day. I didn't take it. My placebo week started on Sunday and today is Tuesday. Where is my period? Should I be worried?
