Thinking of names for my daughter, is みずき a valid reading for these kanji 美月?

I was thinking of japanese girl names for my daughter (due next year), and their kanji writing, and stumbled upon みずき(Mizuki) written as 美月 (kanjis for "beautiful" and "moon"). However, if I look for the reading of 美 I can only find うつくしい or び, not み. I saw that sometimes names make exceptions with kanji sounds, but I don't want to trust random sites on the internet and make up the pronunciation of these kanjis. Can someone confirm this?
