Birth control bleeding

So I’ve been lightly bleeding/ spotting on and off since the 19th. when i wipe there would be pink blood. It started as a reddish brown and then became pink. Sometimes, i would bleed enough to wear a panty liner or a light pad. Most of the time it would only show up when i wiped. I was suppose to start my period yesterday. I started the fake pills last night and still nothing. When i wiped i saw some pink blood. Should i be concerned?

This my second month on birth control. I’m on Nikki. I know it takes time for my body to adjust I’m just confused if I’m getting my period or not? Is it okay that I’ve been bleeding since the 19th? Is that my period?

I’m cramping a little so i assume that’s my period? I also have that feeling when ur bleeding but you check and you aren’t lol
