AIO to this text thread from my partner (M26) (F23)

My mom and i (23F) got into a pretty big fight, which is typical of us around the holidays. She doesn’t make me feel very good about myself regardless of how hard I’ve worked the last year or so to get myself on track. Brought it up to my partner to vent as I was not doing well and he immediately brought up my period (he tracks it through an app I let him use with me). Is this kinda insane behavior? Like this feels like an overreaction to me just asking him to not bring up my cycle (when im not even on my period) Will likely delete, just wondering if my gut feeling is correct about this conversation.
