implatation bleeding ????

I had sex on the 3rd of December the condom kinda had a tear so I  took a levonorgestrel plan b 12 hours after I had sex .... the next 12 hrs I took the second pill.,. On the 6 of December i had sex again with a condom but it was all good no tears .... Now today the 8 I went to pee and I am spotting. It's pinkish and very light but on my under its a like a golf ball size stain of blood . Is this implanting bleeding ??? Or is it because of the pill ??
