i feel stressed ttc #2

it's been months, 7 months to be exact. I've been taking ovulation tests and it has not given me a sign of ovulation. I know I'm using it right because I use it in the afternoon and same time and they all come out negative. I have irregular periods and it's hard to tell. urghh! I'm so fustrated! idk what to do. Glow says that I ovulate this week but my opk says I'm not. what should I do? should I get a different kit? I spent so much money on them already. sighhh... 😢😭 I want another baby so bad!! God hear my prayers!!🙏🙏
