So I started shark week (cycle) last month oh December around the second week and when I get my period it usually last for two horrible weeks and I was expecting it to end last week but sadly it didn't it started off as light then it gets light again then stops but this time it just went light heavy light then heavy and this is like my third week is it normal for it to go that long? And if so my gosh because its suppose to start up again in two weeks or so.. Maybe just a cycle change?
