freaking out

Just started the combined BC pill 2 weeks ago (i started it on the first day of my period). After one week on the pill, my boyfriend and I had sex. We used and condom and he pulled out with the condom. Now, a week later, i wipe and there is light pink blood on the toilet paper. my boyfriend fingered me hard about 30 minutes before so that can be the cause but i’m freaking out that it might be implantation!? my next period isn’t supposed to start for 12 days😬
