24 weeks and bummed out - Literally

Went into my appointment today, thinking we were about to finally find out the gender of this baby BUT the baby had his/her bum out and was facing the wrong way. 🙄 It was hard to tell so my doctor basically said it looks like a girl but hopefully when I come back in 2 weeks the baby will be turned over. Ugh! I am so bummed out I've been waiting so long to find out so I can start buying things but it's always something when I go to my appointment. Should I just go with the "it's a girl" and buy girl things?
