Help TMI

Ladies I need help.. this is my second pregnancy. The past couple days when I go number 2 and I wipe there’s just blood. It doesn’t hurt to go, I don’t really notice that I’m straining or anything. What could this be?????? I’m calling my dr tomorrow btw. Just wanting to see if anyone can possibly give me some advice? Or if it’s happened to anyone else? I’m 26+3.
