Leaking?

So I've been losing my mucus plug for about 2 days now and last night my undies had liquid in them. I thought my water broke and went into the hospital. After a check, the midwife said it wasn't amniotic fluid. Today I went to the bathroom and noticed my undies were wet again. I'm confused if it's amniotic fluid this time or another fluid? I'm so confused and I know I didn't pee myself haha. Anyone have this happen to them ??
