TMI Post! Implantation bleed? AF arriving?

Hi guys! I just want to know your experiences if that's okay and has you AF showed up or have you turned out to be pregnant! I have had irregular periods for the last 3 years from having my implant out and have been TTC for 1.5 years. My periods are always sooo heavy and sooo painful from the minute they start... Anyway over the past few days I have had spotting only when I wipe (pinky brown colour) gross I know sorry and also very minor cramping but this is only a couple of times a day and it is not in any way painful. My belly feels different in a way I can't describe! Has anyone in this situation found themselves pregnant?
