Ovulating twice in one month??

So I have been doing the ovulation tests everyday. 
I thought I had already ovulated days ago- test line was as dark as the control line. But it was oddly just a few days after my 3 day AF ended (that is normally7 days) then today I got another REALLY dark test line that is darker than the control line. 
Period is supposed to start in 9 days.... 
Two questions, can you ovulate twice in one month? 
And if not is ovulating 9 days before your period normal?? 
I normally have a 36 days cycle so I have BEEN told that I should ovulate 14 days before my next AF starts instead of 14 days after AF. 
Someone please help me here!!
