TTC and my period has NEVER done this! (TMI)

Michelle
Okay, so for the last 2 years (26 months if we want to be technical 😏) my DH and I have been TTC. (His second, my first)
Anyways, I can always count on my period to come every. Single. Month. It either comes right on time or maybe 2 days early, but it's always been here. (Yay... 😐)
Anyways, my period came 3 days early and is different than anything I've experienced! Thanks to google, the options are limitless lol. I would like to know if anyone experienced this and whatnot. 
Day one: normally it's lightish. This time I wiped and saw it coming and that was pretty much it.
Day two: normally my heavy day. This time was such light spotting that I stopped wearing a tampon. The spotting is mainly brown, very little red. 
It usually goes for four days, but it's day 3 the spotting is gone.
