No period??!!!!!!!

Okay so I take a the pill almost perfectly. I’ve never fully missed (the latest I’ve been was 3-4 hours only once and when I am late on occasion its usually within the hour) and me and my BF also use condoms. However I’m on the brown pills this week and have no period yet! It’s Sunday and I’m back on the pink on Tuesday. I had one little spot of red once yesterday in the morning then some dark old blood type spotting the next time I used the restroom but then nothing else... is it normal to skip or should I get a test to be sure?
