Hey everyone, im 22 years old and ive always had a perfect 21 day cycle. I mean, my cycles are almost to the MINUTE perfect. Well, two months ago my period was one week late. Of course on the 7th day i took a pregnancy test, it was negative, then a couple hours later i start my period. It was normal. Except that after it was over every time i went to go go pee i *thought* it was a different color. I didnt pay attention at all, i completely blew it off.
