Spotting??

I don’t have a pic don’t worry lol

But I’m 15 weeks pregnant, and yesterday after using the bathroom I wiped and saw red blood. This might be tmi but I couldn’t tell if it was from my poo... or If it was spotting. I used a new piece of toilet paper and wiped again and there was nothing.

I am concerned but is this just minor? Should I call my Obgyn? Idk is spotting normal in the 2nd trimester?
