I felt like a lil.. idk pop I guess u could say, with my last. And usually its a lot at once and keeps coming out for a bit. But everybody's different!
When my water broke I had just come from the bathroom and leaned forward to get in bed and I had a lot of fluid run down my legs and I had a week to go.
Your water will be clear and won't smell like urine. Some will have a huge gush of water and some will just feel trickles. If you aren't sure, definitely go to the hospital to have it checked.
