Did your pamphlet state you would become unprotected? The majority of combined pills all allow for a missed pill without it affecting your protection.
You don’t actually experience a period on birth control, so you’re not “due” to bleed. You can either experience a breakthrough bleed during your active pills or a withdrawal bleed during your break week or no bleeding at all. Any bleeding you might experience is synthetic, it’s not an actual menstrual cycle. All of these things are just side effects of using birth control and it is nothing to be worried about. Bleeding or lack of bleeding is not a sign of pregnancy, as you are using birth control. It is possible that because of what happened you won’t bleed now but there is never a guarantee, bleeding cannot be controlled. There is no way of telling or guaranteeing you that for next month it will be back to “normal” as side effects can change at any time for as long as you’re using the medication for.
