Ocd symptoms worse before period

I'm having awful stomach pain and nausea and it's really worrying me and scaring me

Sometimes I notice my intrusive thoughts cause me to spiral and sometimes not. I've been practicing ERP for quite a while so it's a bit easier for me to not spiral. But I wonder why that happens. Does anyone else have it? Also I'm on medication idk if that plays a role.

I’m on my period and o think my ocd feels a little worse today… I feel anxious and like something bad is about to happen, like I can’t move or talk cause I’ll freak out or snap and do something. Also I had a gronial response about an SA topic and I feel horrible, I’ve noticed that I do have these gronials as if I’m actually into that but idk if it can happen that you have the gronial and think “oh I’m horny, not about this but I am” is that possible? Idk how to say it… also I think I just want reassurance but I’m also scared…
