Bleeding 4 weeks 6 days

Help! This is my 2nd pregnancy. I had no issues with my first. I’ll be 5 weeks tomorrow and yesterday started light cramping and some bleeding. This morning when I got up I had a thick glob of blood. So far all blood is red in color. Still light cramping. I’m trying not to panic bc I know some women do bleed and go on to have normal pregnancies but since this didn’t happen the first time around I’m so nervous. It’s not light but not gushing and heavy, at least not yet. Has this happened to anyone and were you and baby okay? I have a Dr apt tomorrow to confirm pregnancy but I’m going to be calling them today to update on what’s going on.
