Colostrum - 19 Weeks

So my boobs hurt like hell, what else is new? But today I noticed my nipples felt kinda sticky? That's the best way I can describe it, the rest of my boob is dry, it's not sweaty either but my nipples feel sticky and kinda wet but not a soaked feeling. Is this my colostrum coming? It can come as early as 16 weeks but is it gonna get extra leaky in there? 😂🙌🏼
