Implantation Bleeding? Help.

So in the matter of a week 1/2 I took 2 plan B’s. Don’t ask is a super long story that I do not want to relive.

I knew it would probably fuck my body up, and I’ve been experiencing cramps. But last night and this morning I woke up with this. And my period shouldn’t be here until 12 ish days.

I don’t know if I really did mess with my body taking two plan b’s like that or if this is implantation bleeding.

And if it is implantation bleeding when do I need to take a test?

And if your going to comment how dumb this situation is, you don’t know the full story. So please keep these comments to yourself, I’m just looking for advice.
