@ccallas, u will just know trust me I had trembles and shakes and as other lady mentioned fluid will probably leak not your water but just liquid. I would start walking fast on the daily if I was u the pain and pressure u will start to feel as u become almost out of breath is somewhat similar to labor but labor is like 10 times worst but u will start to feel it with walking lots of walking like miles

Watch out for fluid of liquid , contractions feel like period cramps but they come and go and the real ones are in between every 1-5 mins apart but very painful. Hope that helped a little mama @ccallas
