I'm glad I found this thread. I've been reading all the lactation threads I could locate here. Looks like there's been a few.
Anyway, my bf noticed I started lactating two weeks ago, when we were out of town. It was a pleasant surprise though. I was pretty shocked and amused by it. In a few days the left one started to actually squirt. Now the right one does, too. I really don't mind, as I'd previously heard it was possible and can be a different sort of bond for two people to share (my boobies get no peace now).
I don't believe I did anything in particular to trigger it. I've been on spiro/prog/estradiol for 3 years ~ In the past I've massaged them a little daily..just incidental massage. I also took my estradiol shot a week early when we noted it. I also noticed the nipples were feeling a bit sore for a while, like they did in the early weeks of E. But that's all I can think of. :\
Thanks ladies, it's good to see so much information about it. I will phone my endo about this asap now, too.
