One month after pill brown/red discharge

It’s been one month since I’ve taken the pill and i got what I think is my period at my normal time however it was super light and I got no cramps. My period is not due for two weeks and I’ve been having brown discharge mixed with some blood/red WTF is going on? I’m still bloated and scared I’m pregnant. Is this implantation bleeding? 🤦🏻‍♀️
