period problems!!! help!

Isabella
Okay, problem. My daughter is six months almost seven months old and my period had pretty much regulated. Well, I've been on my period for two weeks and it started off as spotting and has progressed to a VERY heavy period. And is showing no signs of stopping. This has never happened to me before. My normal period lasts five days with two or three days of heavy then it dramatically lightens. Is this something that I should be worried about?
