Question for you ladies

Shania
Hello I've been ttc for about 5 months now.  Last month my period started on the 13.  Well what I thought could be a period but it wasn't heavy bleeding it was light and didn't have any blood clots.  And ended on the 14th and lightly spotting on the 15th.  First it was really really late about 2 3 weeks late.  Do you guys think I could be pregnant and that could have been Implaition ?
