weird cramps started Friday unlike any period cramp I've ever experienced. Saturday rolled around still crampy and not like my period. Wiped and a few light pink dots came out. Put a tampon and and all have barely filled the tip of the tampon. Now it's brown and mucusy.. is this implantation bleeding? When I get my period it's HEAVY and the cramps are worse than labor I swear. I am just so confused. It said my period was due a week ago but on Saturday that would have been day 12 aka still implantation period so I'm so confused. Help.
