Hey darl, I had colostrum leakage after losing my 2nd angel, and it continued until just before I got preg with DS, then started again around 15/16wks and got worse from there.
When my milk finished drying up when DS was 6wks old I stopped having leakage, and now (just noticed 3-4 days ago) I have colostrum leakage again. Fingers crossed it's a sticky BFP for both of us this month!
