Boob soreness after already having a baby

Hi all! Wondering if anyone has experienced this.

We are currently trying to get pregnant with our second baby. I breastfed my first for a year.

The first time around my boobs would get super sore right after ovulation and would stay sore until I got my period. And remained sore when I found out I was pregnant with my first.

Now that I have my period back and we’re trying for another, I have noticed no boob soreness or tenderness throughout my cycle. None. Zero.

Does that mean I’m not ovulating? Or is it a normal change after having a baby and breastfeeding?

Any thoughts?? Thank you!
