About 20 minutes ago, I felt the urge to throw up. Whenever I throw up its very forceful and violent and feels like I'm gagging everytime something comes up. Each time I gagged, the pressure Made my bladder empty and it felt like I was forcing myself to pee. Well, whenever I was done throwing up, I got up and there was a big pool of water/pee under me. It's so embarrassing and Has me wondering if something's wrong. I've heard stories of people's water breaking at 17 weeks (which is how far along I am). Is this normal ?
