Yeah, you hit a vein not your muscle ( the muscles are really deep ). Sometimes the bleeding and pain stops a few minutes afterwards but since it didn't for a few hours and you're still getting blood two days later, you might want to change sites. There should be a 1-800 number with the Omnipod where you can speak with a nurse about it during the work day, maybe it's on the back of the PDM, it'll be on their website if you can't find it on your Omnipod.
