No ovulation or is it too soon to tell?

N Baby#1 due 04.01.22❤️

According to my tests I hit peak (solid smiley) on Tuesday early evening.

Glow then said my ovulation day would be Wednesday (yesterday).

I woke up this morning thinking that I’d see a good increase in my BBT?

But nothing really? Just a very slight increase to my normal levels (I had a dip before the suspected ovulation day).

Does this mean I haven’t ovulated this cycle or can the temp increase be gradual? I’m super new to BBT charting, this is my first cycle.

Please help :)
