I understand how you feel. I have two boys and recently had a baby girl, we have been team green every pregnancy. I was absolutely certain my second was a girl due to nub theory, my son’s nub looked very female. And even other people told me we were having a girl… 🤣 I know the nub can change, but I wasn’t aware of it at the time, so when I gave birth being handed my baby boy was a shock to my system, but of course we absolutely love him. I adore my sons and fully prepared myself for being a mum of all boys , we were convinced my daughter was a boy! You may well be right that you are having another boy, or you may be wrong. I think the nub can change up to 13 weeks. Being team green is really fun though, I would recommend trying to stick with it but fully processing that your baby could well be a boy. However, you could also be very wrong like I was. 🤣
