The pill + my period

Hey guys! So I just started the pill at the end of March and my period in April came a week early. Yesterday I was supposed to start my period for May but I've seen nothing so far. I am sexually active and I know being a day late is nothing to worry about, but I have super bad anxiety so my brain likes to tell me other things. Anyway, I'm on a combination pill with 21 pills per pack. I don't have a week where I take that "sugar pill", and I'm not sure if I'm supposed to stop for the week of my period or not. I don't remember my doctor telling me that. My last period was super light and I'm guessing that it was just spotting but I'm just not sure what I should do in this situation. Do I stop taking the pill for this week and start up again? Could that be why I'm late? Thank you everyone!
