lactation ?

Kortney

I was lactating a few months ago and it was believed to be from just being around my pregnant roommate who was also lactating but she's moved out and it's been months since I've produced milk since. I've been feeling extra emotional lately and even got what seemed like a normal period. I took a test a few days after my period but it was negative, maybe I took it too early ? any guessed what's going on?
