Spotting at 2 DPO

I’m very lightly spotting today. According to my glow calendar, I ovulated Saturday. The hubs and I had sex Saturday and Sunday (and Tuesday earlier in the week). Isn’t it a little early to be implantation bleeding? My period is usually regular and I don’t typically have any spotting in the middle of my cycle like this. Help a girl out. Ideas..?
