Is this normal

Courtney

Been trying to conceive for 9 months. I really thought we was pregnant this go round. Day before AF had brown discharge AF started the next day (heavy) the next day was very light (hardly needed a panty liner) then the next day was just a few spot when I wiped. So I assumed I was done my periods are normally 3-4 days. Today 5 days since day 1 I have been cramping and had some pink discharge when I wiped once. This has never happened to me what about anyone else?
