Different blood type from baby, can breastfeed?

My baby and I have different blood types - I'm an O+ and she's a B+. Her jaundice is quite bad, at 298 yesterday and I've only fed her formula so far. But now that my milk has come in, I want to breatfeed her. Is it safe for her? Will it get rid of her jaundice? Or should I do both breastfeed and give her formula. Please advice, I want her to come home from phototherapy 😔
