Glow help

Glow said I ovulated 6 days this month. 6th-12th. If that's right then I started O a day after af. Does that sound right? Next month is set to be the same. I'm just confused because I was tracking O by Glow and I did some research and it said woman O only 4-5 days. I just feel like Im trusting this app and it may be wrong. Internet says woman ovulate 10-14 days after their cycle and that is not what Glow is telling me. I may be trying when its not time and missing when it is. Anyone else have this issue?
