Can someone please look at these and tell em what’s going on?

Currently cd 15, am supposed to ovulate today according to <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>.

DH and I got pregmate strips to help us track better but if I’m supposed to be ovulating now wouldn’t these be darker?

A little background my cycle is typically 28 days long but last month period came 2 days late throwing off the app. So I think I ovulated on CD14 (yesterday) and now CD15 today like this app predicts but idk.

My question is shouldn’t these lines be darker? Does this mean I’ll ovulate later than we thought? I’m so confused and I’m a first timer using the OPK!
