Help!

So im bleeding red but it's not heavy only when i wipe should i be concerned I took a test cause I have some left and it's still dark i should be 4 weeks and 5 days according to my lmp i am not cramping

Update: didn't last long it disappeared as soon as it arrived im now spotting light brown also i did get checked at the er because of an "ectopic scare" and everything was fine.. though they couldn't see baby or heartbeat they said everything was normal and fine yes I know things can change in an instant but I'm not going to work myself up over it
