Confused :/

Samie • Samie, 22, University Student, Fiancée to Adam, mummy to Lilly Jayne & expecting baba number two in August :)
So what I think is AF started on Sunday (3 days darly).., I bled for a day and then last night it randomly stopped, still not come back now.
​It was slightly lighter than usual but was really pink.. Sound like IB or just a weird period?
