When did I ovulate? Is glow correct?

This is my first month taking temps, me and my partner have been TTC since December 2014, so I've decided to give this ago, on cd10 it said I had a 'spike' and it continued to rise after that.... Yesterday glow said that I had ovulated, but I have very irregular cycles they can be anything from 20-63 days literally! 
Over the weekend, for the first time ever I had Ewcm with traces of blood in it (never had it before) 
I thought it could be down to ovulating... But now I'm thinking that would be 9/10 days from my temp rise, could it be implantation bleeding?
