Bed wetting?

I’m 18, I’ve struggled with bed wetting since I was little. It kinda started to go away and would only happen occasionally. The past month it’s been happening every time I sleep that hasn’t happened in almost a year. I’m concerned as to why it happening like that again. And I don’t have diabetes, I do have trauma and nightmares but that doesn’t seem to be what’s contributing to the bed wetting.
