In my oppinion your ok.Unless there is odor or itchy nipples or any other sign of infection. I gave birth 11 months ago, I stopped breastfeeding 5 months ago and if I squeeze my nipple I still get a bit of milk...its not really milk though, It looks like the colostrum (the liquid that comes in before you get your milk supply). If it makes you nervous call your Dr and have her look at you....never hurts to be safe.
when i had my daughter i tried to breastfeed but it did not work out for us so i stopped, but my milk still kept coming out when i squeezed. i looked it up on line and it seems to be normal. but like the others said if you are still worried call your doc. i know i was a little worried at first.
