New Experiences

Today I experienced lactation for the first time... I am 28 weeks & 3 days. At first I just felt wetness on my shirt and didn't think much of it... but my nipple was wet. I moved on until it happened again. I'm feeling nervous and saddened but I don't know why or understand why I feel sadness. FTM... I read that it's normal but I guess maybe the changes in my body are throwing off my feelings.
