Is it true that when it rains on your wedding it’s bad luck?

Unfortunately we live in California it’s almost December and it has been raining I hope it doesn’t rain that day 🤞🏼 since it’s also going to be outside. I say this cause both of my sister in laws were telling me its bad luck when it’s raining and your getting married that day Idk if thats true idk much about marriage superstitions. I’m stressed already and for people to me telling this I’m mean it’s not helping much. My husband and I are aware that it can rain. But yeah
