yay! pregnant! but when did I conceive??

Roseanne
Took a test today and it was positive. The line was very dark. The strange thing is that I am only 9dpo. I took anclearblue ovulation and ovulated on day 19. I took a test thinking if there even was a line it would be barely visible. Could I have conceived way before my ovulation day? Thanks for your help! 
Hoping for rainbow baby after two losses <3
