Need some advice please... not too sure what my body is telling me?

sometimes you get these symptoms from stress probably wouldnt be having the back ache or nausea this early on usually it occurs when you are around 6 weeks or more pregnant. also abdominal cramps arent really something situated with pregnancy and coming off the pill can most deffinately cause spotting. doesnt sound to me like your pregnant but take a test 4 days after the bleeding. if its positive congrats, if not than i would consult with your doctor
