I don’t know what test!!

Hi all. I had a weird period this month, I am on birth control, and for peace of mind I want to take a pregnancy test. I started my placebo pills this week and I start a new birth control pack tomorrow. I plan on picking up a test tomorrow night and taking it Monday morning. What test should I get? I know pink dye is the best but I don’t know what brand... And should I get digital? I plan on going to CVS.
