Does ovulation tests really help anyone?!

Shamekia
My husband and I have been TTC for about 3-4 months now. However I never use ovulation tests I just go off of the fertile days and estimated ovulation date that Glow gives me. My periods are usually on schedule with what Glow says so that's why I depend on it so much. However now I'm starting to think this maybe hendering us from getting pregnant. Has anyone got positive results after using ovulation tests instead???
