Light bleeding/15wks3days

Cierra
I am 15 weeks & 3 days, my SO & I had semi-rough foreplay, & I have light bleeding, & only notice it when I wipe, it's 2am or I'd call my DR. Should I be worried? Is this normal? It's very light pink, & I kno when you're pregnant the blood vessels around your cervix and such is much fuller; just want everything to be okay.
