Is this a sign?

I’m not sure if I’m a firm believer in “signs” but I had my baby shower last week and had 5 helium balloons, all different pink balloons etc, but the only balloon that has sunk and nearly deflated is the one that actually looks like a baby?

My mum joked around saying it’s a sign baby girl is coming soon!

All the other balloons are firm and upright, only the baby one has sunk🙄

Sign or not? Am I just being paranoid about every little thing because I can’t wait for baby girl to arrive👶🏼
