Did a pregnancy test!

I use this glow app and I had sex when it said I was ovulating . I stopped ovulating last week and this morning I decided to take a test 😭 test said it was negative I also had used the pre-seed. I really feel like I can not get pregnant . I hate to lose hope but when you been trying for months and nothing had yet to come it's so frustrating!! I will continue to try other methods before going to my obgyn. I'm so sad .
