So , for he past two days I've been having spotting (light pink) on and off . The first day , it lasted from 2pm to 10pm , the second day (yesterday) it was on and off on and off . I bled a little , (light pink wig a little red) , around 10 last night and I woke up to nothing this morning . Well , when I went to wipe , it was darker blood and it only see when I wipe . AF is due today . What's going on?
