Spotting 2 days before ovulation

Noel
Hey ladies, this cycle I bled just a small amount for 2 days prior to my expected ovulation. I ovulated within a day after the bleeding stopped. I read this is called ovulation bleed and can be common as well as a good fertility sign but this is something that has never happened to me. Does anyone else have any experience with this and for those who did, did it happen to be your lucky month for conception? 
I also read it could be from low estrogen levels and lead to no egg being released. My gut thinks this to be true but my heart is hanging on to the prior.
