You need to count from the first day of your last period, not the end.
Answeing your question yes it is completely possible to hve a nice dark second line nearly two weeks after your ovulation. Congratulations!!
And as others mentioned technically, you’re two weeks pregnant, but medically it’s considered four weeks because pregnancy is counted from the first day of your last period. That’s why pregnancy is 40 weeks and not 36, even though it’s about nine months.
I have no answer to your question as still waiting for a positive, but just wanted to say congratulations! 💕✨
