Feeling the need to walk back statements about my gender.

Kind of a weird phrasing I know but I couldn't think of a better way to phrase it. I've been questioning my gender for a few weeks now and I'm coming more and more to the conclusion that I am trans. I've been using she/her promouns with my friends and trying out dreasing femme. But every time I say or make a definitive statement that I am trans or that I am a woman to someone I feel the need to walk the statement back and make it into an if I am statement. Has anyone else experienced this?
