Boyfriend says rude things about my period

Ok gals, super weird post coming.

I'm over 5 weeks late on my period. For the second month and my hormones and emotions are all crazzzy . so sure I get a Lil fussy and bitchy lol . but anytime my bf and I get into a argument no matter how large or small even just a disagreement (which only happens conveniently enough before I start my period) but y'all I swear its not always cuz I'm about to start. And he ALWAYS says yeah go ahead and bleed out ! You know your about to start your period thats why your being such a bitch . and I mean like says the meanest stuff about my vagina and my period. At this point I'm sick of it. It pisses me off more than anything. I feel like idk shamed or something for having my period. Saying rude things about me bleeding only makes me 10x madder then our argument gets worse 😦

Idk at this point I'm sick of it. That's literally like our only problem. Idk what to do or what to think... Any similar situations or comments?
