Sprintec & period help!

Hey girls!

I’m currently on my third pack of sprintec. Last month I got my period on the last Friday of active pills. I’m currently on CD30, today is my first inactive pill. I did miss one pill this pack, and doubled up the next day.

I took a hpt which was negative on Friday. I’m confused am I late or does it take time with sprintec to regulate your cycle?

Thanks
