Ovulation test

Elle

Im in my ovulation window (9/17-9/23) and tomorrow is my "fertile day." I've been testing everyday for 1 1/2 weeks now (because I bought a bunch that came in a pack so why not lol) and all ovulation tests have been negative..I know I have time but I'm worried I'm not going to see a positive ever. Just curious if anyone has used these ovulation tests and have negatives but still ended up getting pregnant?
