I feel I ought to know the answer to these, but just to reassure me...
I'm 26 weeks + 6 and the last few days I've had a little bit of clear fluid seep from my right breast. In some ways I'm reassured that they can produce something as I'm keen to breastfeed, but have been nervous about my ability to do it as family members have struggled to exclusively breastfeed for as long as they wanted to. So:
Is this colostrum?
Is it usual for one breast to produce it before the other?
Will there be plenty of colostrum for baby after birth if I'm producing it prior to the third trimester?
Is now the time to start with some kind of breast pads?
I can see that some women might find this all a bit inconvient, but its actually making me a bit excited that my body is really gearing up for this baby, and I've been feeling the baby's movements stronger over the last few days (was a bit surprised the first time I felt the baby move at one side of the bump then the other, I suppose baby was stretching or moving position) and feel really connected to the little one. I suspect its these bonding feelings that have resulted in the leakage! 
I can do this thing, right?
