quick question for you lovely ladies

quick question so my son is 2 years old, my milk never fully dried up (not enough to pump) but enough to come shooting out my nipples when squeezed. So my husband and I are TTC#2 and my nipples have been all kinds or prickly tingly, boobs heavy well tmi my husband was do his freaky thing when he stopped pulled back and said thats weird usually when I suck milk comes out unexpectedly, so out of curiosity we checked them and nothing was coming out!!! we've had two faint lines just waiting again to see if line gets darker. but has this happened to anyone else?
