Implantation bleeding?

Casey
Ok, so I ovulated on the 5th. We had sex the whole week leading up to ovulation and even a few days after. We even used the stork otc thingy this month. Everything has been fine and normal today and then all of a sudden...bright red blood and sort of a lot of it. Could this be implantation bleeding or should I be worried about something else? I'm tired of BFNs :(
