When did I ovulate? (Chart attached - first PP cycle)

[Feronia]

Hi, I’m in my first postpartum cycle so it’s very long, and I’m also nursing throughout the night so I’m getting very interrupted sleep. My peak day was on CD 26 – I had loads of EWCM and my cervix was very high, soft, and open. It was obvious. Then the next two days I dried up and my cervix was hard and closed, so I thought I had ovulated. However, I didn’t get my temperature shift until CD 29!

I know that the sleep is disrupting my temperature at least a bit because one day I woke up super early and temped – my usual, pre-ovulatory 36.9. Then DH took baby in the morning and let me sleep in so I got 3 hours of uninterrupted sleep, at which point I temped 37.2! I marked that one down since it was at the time I usually wake up, but the uninterrupted sleep made a huge difference.
So when do you think I ovulated? My peak day (CD 26) or the day before my thermal shift (CD 28)? Thanks!

Looks like you ovulated on CD28.
