implantation like a period

[ktsl123]

So I have been keeping track of my cycle since May07 and I am always at
33 1/2 days between periods. This month I got my period 5 days early...I am not stressed or on a diet or anything that could do this.

I always get cramps for a few hours after I start my period and then it goes away, but this month I have had cramps for 2 days. I am not sure if it could be implantation bleeding because the flow is the same as my period usually is.
What else can make a period early? and I also don't get why this cramping is lasting so long......Can anyone help??

sometimes your periods are just off once and awhile. Maybe you have always had an 'off' cycle but just didn't really notice it since you weren't ttc at the time or charting and such. If it were implantation bleeding than it would differ from your normal period as far as constancy - like spotting and coloring. With cramping, I am sure it is a sign of implantation too...Just make a note of it and if you have anymore symptoms with being preg, test When did you start your period??? I have read that implantation can occur between 5-12 days after fertilization. best of luck!
