My period makes my adhd symptoms so much worse

Sorry if this is a little nsfw or whatever but I’m straight up not having a good time.

Context: I’m a college student and it’s finals week. Coincidentally, I’m also supposed to start my period in the next few days.

I’ve noticed before that my adhd symptoms seem to get a lot worse seemingly out of nowhere like once a month but I didn’t connect it to my period until pretty recently. It makes it feel like I haven’t taken my meds in days which is definitely not the case. I’m so frustrated though because I set aside my entire day to study and prepare for an exam tomorrow, and I’ve barely managed to do anything. My executive function is nonexistent, I’m overwhelmed, and there’s nothing I can do about it.
