help!!

So I had sex 11 days ago twice. I’m on the pill but I take it wishy washy. He didn’t come inside of me. Yesterday I had (the pictures shown below) this weird stuff in my underwear and light brown when I wiped. This morning i’m having like sharp cramps in the front of my vagina. I’ve felt these cramps before, but I took my pill and i’m not on my period? I’m scared it’s implantation and that i’m pregnant
