Birth controlBirth control

I took birth control a couple days ago, only 2 pills 2 days, and today I went to the bathroom after intercourse and there was light pink spotting. I feel like a couple birth control pills won’t do that, Also last week was my ovulation week and we’ve been using pre seed as well, so I’m confused which it could be from I guess. I forgot you were supposed to Start taking birth control after your next. So I stopped taking it I haven’t been taking my birth control for a month or two prior
