I leaked from very early too and yes it was tinged yellow but thats normal too. I would wear breast pads if i was going out and worried about it so maybe get some for just in case. I also (even for when BFing) keep a spare top in my car for emergencies. When Bfing i have occasionally forgot to put some in and then i feed from one side and the other goes mad and its not a good luck whilst out lol.
