Noa or Noah?

So i recently asked about the name Noa in another subreddit and a lot of people kept saying that it was a completely feminine name in Hebrew. I am not Jewish so I didn't really know that. I prefer that spelling over Noah since funnily enough the Noah spelling feels too masculine and I want a neutral name but I dont know. I personally pronounce it the same as Noah. I don't really live in an area with a big Jewish population so most people will likely assume Noah when I say it anyway. I guess my question is which spelling should I go by or should I go back to the drawing board?
