Ectopic pregnancy?

Had a positive pregnancy test. I would only be a month and a few days along. Started spotting dark blood today when wiping. No cramping. I feel uneasy, light headed at times. I started with a really intense back pain on upper left side kinda at bottom of shoulder blade. Its constant and flares. Sometimes with movement and sometimes i feel it shoot to front or wrap around side. I have no history of ectopic. But have a hard time carrying a baby due to abnormal shaped uterus. Bc of this i have recurrent miscarriages. With spotting feel that may be happening again except not really cramping. Really just looking for insight on this pain. Has anyone experienced??
