Eggy breastmilk?!

I’m exclusively pumping/combi feeding and the last day ive noticed my expressed milk in the fridge smells of egg! I have a sicky baby anyway but has spit up smelling of egg now too… I had eggs on saturday but the pumped milk is from yesterday/sunday soo i’m so confused! Is something wrong with my milk or is this normal? I’m 10weeks pp and had really bad period pains yesterday and mucus discharge… not sure if that affects milk?
