Cramping and bleeding

I’m 5 weeks and 1 day but I’m having bleeding and some cramping. The cramping isn’t as bad as period cramping it definitely feels different but still slightly uncomfortable. I’m not extremely worried about my back pain because I’ve had that the entire time I’ve been pregnant so far. But did anyone else have bleeding? I know I had it with my first pregnancy but I have IBS this time around so the bleeding is making me nervous. I don’t really want to run to the doctor yet because even if I am having a miscarriage they can’t really do anything sadly.
