Last night getting in the car, a gush of discharge came out and when I went to the bathroom thinking maybe I was bleeding (because it felt like a blood clot came out) I had more discharge come out like water almost and the discharge on the liner was white and could of been sticky? I called my OB left a message but has this happen to anyone else? When should I be worried? It's my first baby I'm exactly 25 weeks today.
