It's definitely not af, it's far too light. I have been using tampons on and off because I keep assuming it'll start, but I don't need them. I had pink cm one evening, then next day little bit of dark on tampon so thought yep here she's comes, just a slow starter this time. Then rest of that day and yesterday light brown tinged cm. Nothing as yet today. the longest cycle I've ever had is 28 days and I'm now on cd30.
