HELP ME!!

So I finished my period Monday 9th, and started my pack again

I left it at my place and couldn’t get it, so I missed 3 pills

I’ve had sex pretty much everyday, each time he’s pulled out

Anyway, I’ve been masturbating for about 30 minutes. ONLY clit stimulation, no penetration. Finished, went to the toilet and wiped and blood was all over the toilet paper?!?

What could this be!!!
