I have really heavy periods and this month I was like 4-5 days late. I got my period on the 17th but only for 2 days and it was very light which is strange for me now I'm spotting! So I don't know if I'm pregnant? I'm taking a p.t on Friday to make sure.. I hope I am! I'll let you guys know.. has this happened to anybody?

Depends when you have had sex.
