"yeah, every women acts the same way on their period, oh please" said my boyfriend. How do I deal with this?

He said I can control my emotions. Yes, I can. But, I find it hard during this period. Everything seems hard to control. I already am feeling bad about myself for gaining weight. And something like the phrase above being said to me is really hurtful. Am I not allowed to be emotional when I'm on my monthly cycle? Which women are allowed and which are not? Utterly ridiculous.
