Hello my period has been abnormal for the past three months! First my period came 3 days late, then it came five days late, then it came six days late this month and it wasn't even blood it was dark brown but very light? My nipples hurt often and I have cramps here and there? Plus some days I don't even spot at all unless I see some brown on the toilet paper after a wipe! What's so unusaually is that I don't feel OK and its still happening and its been over five days now? I'm really scared?
