Cycle Regulating or Implantation Bleeding?

Melissa
I recently got married (Valentines Day this year) and ever since the month before the wedding my cycle has been out of whack. It has been coming later and had gotten quite consistent in how late. This month in the middle of when I was SUPPOSED to be ovulating according to Glow I am now bleeding. I am not having cramps as bad as usual, the bleeding is lighter, it doesn't feel like a normal period at all. Could this be implantation bleeding or is it just a funky period and my bodies way of getting back to normal from the stress?
