Ovulation help!

Nitzaliz • Due Dec 1st💘
So I'm confused and I need some advice from anyone who is willing to help :) 
On the 11th of this month 2 days after my period ended I decided to test the ovulation test strips and I got this.. I posted on here and a lot of people to me it's positive 
The next day 12th I got this 
So I thought after this I was out and I only BD on the 11th
Today out of curiosity I decided to test again and I got this 
I think this line is darker than the one before it and I'm just confused like did I ovulate or not yet? And should I keep BD?
