This post is for people who don't bleed on their period, but have the cramps and mood swings. This post is for people who don't have periods at all. This post is for people who only have periods once every year or few months.
You never HAVE to have a period for any kind of identity, whether that's being intersex presenting female, a trans woman, femspec, or even just a cis woman. You should never feel out of place because you don't have a cycle. It's not weird to not have one, it's not weird to have a bloodless one, and it's not weird to have one that fluctuates.
You're still valid.
