My period was five days late, I have regular28 day cycle/no stress or anything but it was suppose to come on August 26th but came on August 31st then went off September 2/3.. it just came back on today I was spotting around 12 today when I was at work now I’m off I’m cramping/bloating and having back pain really bad but the flow is light. Have anybody else went thru this?
