So I'm torn between deciding whether the tiny beads of white balls I've found just sitting on my breasts are residue from our washing powder, or colostrum. I have not had a positive test yet but I am on cd45 with no period and have experienced most preg symptoms. Even though they come and go. The most recent one has been sore nipples! Our of curiosity I crushed one of the balls between my nails to see if it would break because it was quiet hard and it turned to powder. Any ideas ladies?
