Double yolk?!?

So I was making myself an egg sandwich this afternoon for a snack. I cracked the egg and double yolk😳 I’ve heard and read about double yolk of being an old wise tale where it’s a sign of pregnancy!!! I’m hoping it’s true as me and my man have been trying for a year!!! I just want to test right away but I gotta hold on until Friday/Saturday when my period is suppose to come😩 hopefully AF is not coming this month & our rainbow baby is here! 🙊💙💜
