I need help to ease my mind so please...

So I’m almost 25 years old, and I got REALLY turned on last night, i used a toy I normally don’t (yes its an actual vibrator not a random object) and it really hurt when i was done and took it out, no other pain than that, I went to the bathroom & I saw a little bit of spotting like bleeding, it’s very light and pinkish color & ONLY happens when I wipe! It’s VERY possible that I’m pregnant (but I think it’s too soon to tell, I’ve been waiting for my period in 2 weeks) when will the bleeding stop? Should I call my doctor? Why did this happen??? 😭
