im so confused help ladies!

Okay so about 7 days before my period was due i had light bleeding. At first it was brown and mixed in with my cm so it juat looked like creamy brown cm. Then it was kinda pink and stayed light and i only had it for a day or two, maybe three. Well my period was supposed to start on saturday, it didnt come but then yesterday i had light light light bleeding that was a mix between red and pink. I had missed two days of my bc so could the bleeding been from that? I took the two pills and bled a little bit longer and today am still bleeding vvvvvvvvvery faintly. Could it have stopped from the pills? Could i be pregnant? Im so so so confused so please any advice!!!!
