Breastmilk leakage during pregnancy

Just want to ask guys kung naranasan nyo rin po bang magkaroon ng breast milk leakage while pregnant? I just experienced this last night. Nagising na lang ako ng madaling araw na basa sa may left breast ko, and nung natuyo sya, nanigas na halatang nagkaroon ng leakage. I tried searching it sa internet and it says normal naman daw, nagmessage na din ako sa OB ko, but wala pang reply. Kayo mga Mamsh, naexperience nyo din po ba yun? I'm 17 weeks and 4 days pregnant and a FTM po. Thanks a lot.
