Spotting or period?

I had a really weird period this week. It started on the 31 and it was very watery and pink. Then on the second day it became a little heavier and darker but nowhere close to what I normally deal with I wasted about 3 regular tampons  because there was nothing on them but I kept having to use the bathroom. Then this morning when I woke up it was complete gone which means I only had it for 2 days. Me and my fiancé were trying to have a baby but it hasn't worked out yet.
