Hey, My Name Is Demetria. I'm 27 Years Old And

Hey, my name is Demetria. I'm 27 years old and trying to conceive. Well I had my last cycle on August 28, being the first day. It's been a normal 28 day cycle until today. I'm bleeding and it's kinda heavy with light cramps. I'm curious about it being my cycle or implantation bleeding.
