question

Okay so question.... according to Glow I was ovulating this past weekend. It's always been fairly close to accurate on my period the past few months (like within days) but I have never taken ovulation tests until now. I was curious so I started taking them Monday (which was supposed to be my highest ovulation day according to the app) but every day I've taken them it has said I'm not ovulating.... we have had sex every day over the weekend while I thought I was ovulating as we are trying to get pregnant. Is there any way I could be pregnant and it is not saying I'm ovulating for that reason? Originally I was supposed to start my period the 27th but it has now moved to the 2nd because I keep logging that the test say I'm not ovulating. I've taken pregnancy test and it says negative but I think it's too early to detect that. Any advice helps!!!
