Starting to change my mind am I nuts lol

I am pregnant with my 4th I have 1 girl and am now on my 3rd boy, this was suppose to be my last baby but I’m kinda changing my mind I know it’s 50/50 I really want another girl and I know I can financially support 1 more we don’t use daycare we’re making renovation in our home and adding extra rooms, we have a van I feel like people are already judgmental about the 4 we have I swear people do not believe in big families anymore🤣 I always said #4 was my last but I’m not sure I’m ready yet am I insane for feeling this way? I’m also only 27 and if I did have another it’d probably be a very long while after this one who knows I’ll probably change my mind anyway after this🤷‍♀️
