That’s the start of your colostrum starting to come in! Totally normal, it freaked me out at first too it’s adviced not to extract untill after,I think, 36 weeks (what I was told by my midwife)
Yep as Morgan said, it's not discharge it's your colostrum. It can be a range of colours mine starts clear then goes cloudy white. Some people have bright yellow/gold etc. Try not to squeeze just wipe it off as you're not meant to colostrum harvest til 36/37 weeks x
Yes this is normal it’s just your boobs getting ready for milk it will become cloudy soon like milky
