Ovulation help!!

Hello everyone.

My cycles are usually 31 days long.

1 is CD 13

2 is CD 14

3 is CD 15

4 is CD 16 (today)

When does it mean I will ovulate? Today? Or how exactly do those work?

Should I continue to test and bd since it’s possible I haven’t actually ovulated? Ugh 🫠

I had ewcm like 3 days ago. Today my nipples are tender. Those are the only symptoms I’m feeling.

I don’t want this to change your judgement but I do have pcos and sometimes with that, the body tries ovulating several times.
