well dear as odd as it seems, it does happen when estrogen levels decrease rapidly
and as Nicky said it is an increase in prolactin thats causing it.
Wow dear your pregnant

..... OK not really but like Paula said your body thinks
you are.
I had that happen to me at about 7mths. in, I was having $$$ problems and could not
pay for my script for like two weeks and right near the end of my lapse it started and
didn't go away until I switched inj. and got the E levels back up and that was at 9-10
months in
I was told by my doctor that it was nothing to worry about but that it would be best
if I didn't stimulate them cuz it would only prolong it and could cause engorged breasts.
At first I was like ooh! engorged breasts are larger breasts, but then thought about all
the nursing mothers and thier horrer stories about engorgement....suffice it to say that
I did not touch them after that except for reluctantly light grazes when in the shower,
until I knew that I was no longer lactating.
New experiences....gotta luv em sometimes
*Hugs* Nicole
