Am I on my period?!?

Jen

So I just started birth control to regulate my flow cause usually I would get 9 day periods were I’d puke 3 times a day with terrible cramps. Anyway. This is my first month taking the pill and I’m on my placebo pills so this is when I’m suppose to be on it. But my flow is so light I’m only wearing a liner out of shear paranoia. When I wipe after using the bathroom is when I see blood but other than that I don’t have any blood on my panties; only weird discharge! Am I on my period? Is my body still trying to get used to the hormones? My birth control is aviane which is both estrogen and progestin. I haven’t any side effects while on it. I only got cramps my first day on the pill but now it’s been 3 going on 4 weeks on it and I’m fine.
