Period or pregnancy?

Amanda • 🤔
I've had sex for the first time. 
So I had sex twice. And I let him put his tip in. Without condom. But no pre-cum or ejactualtion was there. And he just put it in. And took it right out cause I was dry and it hurt him. 
I've been spotting. And yesterday I got a good amount of blood dripping out of my vagina. And it looks exactly like a period. But today I didn't have any blood...I know I'm not pregnant. My period isn't due until next week. I haven't been experiencing any symptoms of pregnancy. It's just this blood has been freaking me out like crazy. And everything online is saying its Implantation. And so it's scaring me and stressing me out. Please help me.
