Sensitive nipples and sex

This is posted anonymously bc I don't like talking about my sex life like this

When my husband and I were BDing (TTC) my nipples were extremely sensitive and like in a turn on way. When he was touching them it was like almost better than the sex itself. That's WAY not normal for me. I miscarried about a little more than a week ago and ttc again after that loss.

I'm wondering if that can be a sign of ovulation or a symptom of after miscarriage or idk

Why the change now?
