Okay, so I got out of the shower just now, and I noticed something funny on my nipple. I messed with it a little bit and squeezed and this cloudy liquid started coming out. Am I lactating or is it something else?
Here's some info that might help you out:

I am not pregnant (I'm positive.. I just ended my period and I haven't had sex since then), I have never had any infections, I am on birth control, I have inverted nipples, and this has never happened to me before. Please, can anyone tell me what this is? I'm so freaked out!
