Period after positive?

My wife and I received a positive pregnancy test last week and we were so excited. We took a few other tests and some were negative some were positive. I was 12dpo when I got my first positive. So still pretty early.
Then I started bleeding. It was light at first and got heavier for two days. 
My wife has looked up so much info on what this could be. 
Has anyone else experienced this?
