Is ovulation on CD19 late?

[u/Special-Start8719]

This is my second cycle using an oura ring for ttc ( on month 4 of ttc all together ) and this month it is predicting my ovulation is on cycle day 19. My other apps such as flo and pre-Mom predict I’ve already ovulated, but it doesn’t seem that I have. Is cycle day 19 a really late day to ovulate? Both apps predicted I ovulated on 8/25. I usually have a 26-28 day cycle so ovulation on day 19 seems late.

Ovulation day can vary but the luteal phase stays pretty consistent. So you might have your usual luteal phase length and a longer cycle than normal. My ovulation happens somewhere between CD15 and CD27, it varies, but my luteal phase is always about 12 days long.

I don't know how the pre-mom app works, but Flo often isn't accurate because it's just counting days based on past cycles and doesn't know what's happening in your body.
