Ok, so I was 4days late on my period which is really rare for me.. and I started it this morning, and now it is still a really light flow and a light pink/red color. I took a home pregnancy test yesterday and it said negative. But I show signs of early pregnancy! I'm tired, tender breasts, moody, and this would be the "week 4" stage where spotting and nausea come in which I have been nauseous too... well when I started my period this morning... It was only spotting and then picked up enough to wear I needed to use a tampon but when I changed it... It was really light pink/red which it never is.. its normally a dark steady flow! Even though the pregnancy test said negative coould it have been a false negative? My ovulation day was October 3rd, 2012 and my bf and i had sex and he came in me on that day! My first day of my last period was Sept 19, 2012...
