I'm cleaning my house and tmi, but not wearing any pants. I've been having what I think are Braxton hicks all night and a dull pressure on my tail bone/ butt which I assume is sciatic nerve pain. Anyways, I keep noticing a small drop of water (fluid) running down my leg, and it keeps happening after I wipe it off. It's a really small amount and I don't feel anything come out like I do if I sneeze and pee a little lol. Has anyone experienced this?
