IB or normal period..

Annie • 💍10/7/17💍. 🦄Mom to a beautiful baby girl🦄 .
I've never ever in my life had a light period. It started on Sunday and wasn't supposed to start until Tuesday. I'm still bleeding but it's super light pink and brown. Tuesday I didn't even bleed at all. I don't know if my period is being wacky or if it's implantation bleeding/spotting. Like I said it's never been light and I've never spotted before. Please help!
