OMG! Am I really lactating already?

I recently stopped by Victoria's Secret to try on some new and bigger bra's. Just something to get me by until the baby comes. First I must tell you that I was actually wearing my sister-in-law's hand-me-down nursing bra because it was the only bra that fit me at that point. I went to try on some new bra's and noticed I had wet spots in both cups of the bra where my nipples were. WHAT??!?! What the f*ck is going on? Am I lactating already?? Do my boobs think I need to lactate because I am wearing a nursing bra? Is this normal? Should I start pumping now in case the colostrum and milk dry up before the kid comes? I logged onto google and typed in, "Is it normal for your breasts to leak when you are pregnant?" The answer..."it's typical in your third trimester." I am only 24 weeks! Apparently if your breasts leak early it is supposed to be a good sign that breastfeeding will be easy. I hope so! It has become quite a funny thing in our house. I woke up last Saturday morning with wet spots on my t-shirt and Trevor screamed, "Oh my GOD! You are lactating!" He thinks it's funny. I think it's gross. The good news is that I now wear a size 36D bra.
