Hey everyone! I have lower back pain, especially on the left side of my abdomen. It's like false contractions every 5-10 minutes at night. By morning it's gone. (The false contractions have been going on for two days now). Am I in labor or what? Every 15-20 minutes I need to use the bathroom (pee is white, if I hold it too long then yellow, krrr... you won't understand ???‍♀️), there's discharge sometimes white and sometimes clear. Should I call an ambulance or not? (If it's really bad, yes, but only if it hurts.) I'm a first-time mom, I don't know anything
