Last night I was having what I think were Braxton hicks. On and off all night I've been having dull cramping, not painful just uncomfortable. When I woke up this morning I noticed my panties were pretty wet. I can't tell if it's discharge or amniotic fluid. It's totally clear like a water stain, and smells sweet so I doubt it's urine. I'm 18 weeks and freaking out a little has anyone have this happen to them? (still cramping btw)
