My husband and I were ttc for 7 months and got a bfn every time, this month I tried ovulation strips and got a positive!! Everybody is different and everyones situation is different. But for me I feel like it was just timing.. My ovulation was a week off from what glow said it was. Glow said I was supposed to ovulate on Jan 20. But ovulation strips said I was ovulating Jan 14!! That’s a pretty big gap. So I wouldn’t just rely on glow!
