Implantation Or Start of period?

Mackenzie

So I feel even crazy posting this, but I went through my whole day no cramps or anything. I came home tonight & there was blood in my panties, ok whatever normal. Go to my <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> to put the start of my period, realized its only the 9th and I wasn’t supposed to get my period for another 4 days. My breasts were definitely sore this past week but that usually happens right before my period. I could just be freaking out. (My s/o and I just broke up) the last time we had sex was my last day in my “ovulation period” according to the app.

Anyone have any thoughts? My period is never ever early/late. Has anyone ever experienced this before?
