answer:  it doesn't really mean that you are pregnant again. your milk could be fading away and then will disappear. Most of the time milk is done on supply and demand. so whatever stimulation to the breasts or hormones alone will cause milk to be there. but in order to maintain flow there needs to be much more stimulation. I don't know if you pumped at all after that first 8 weeks but that might also be the reason why there was more. It is possible that you could be pregnant again but I wouldn't rely on breastmilk consistency to find out. I would take a test to be certain. esp if you have missed your period.
