Bitchy?

I have been seeing this guy for about a month now. We haven’t had sex but have some nice make out sessions, hold hands, go on dates. We talk naturally and like hanging out.(well at least I do) We are taking things slow and haven’t made clear what we want. We text everyday and it’s nice. Idk why but I feel like I just want to not talk to him for a day or so. I really like him but I started my period and I’m being emotional. He’s too good to be true I guess. Is it bitchy to just not talk to him for awhile with no explanation? Or just never talk to him again?
