Use they/them pronouns w She/her?

Hello there, I’m a little nervous asking this as it may be touchy to some people and I just hope I can explain it properly. I’m a female that uses female pronouns. But I often times use “we” when referring to myself and I find some sort of... comfort(?) use they/them pronouns. I know there is gender fluid but I don’t see/think myself as a man or anything but find myself using they/them more and more. I guess what I’m trying to ask is: would it be okay to say my preferred pronouns are she/her and They/them? Idk if that is even a thing. I apologize for this. I’m just a little conflicted and need some other opinions on it. Thank you
