Hi. I'm a FTM and I have been having one hell of a night. I'm 40 weeks tomorrow and I am not sure what is going on with my body. I think I lost my mucus plug tonight, no blood just brownish thick mucus after wiping. I have had extreme nausea and dizziness tonight, and I feel really shaky and jittery like my heart is racing. I have been having lower back pains that come and go like contractions for days butt are not consistent. I don't know whether this is the start of labor or if I should call my dr.Had an appt 2 days ago and was 2 cm diliated and 70% effaced. Please, any advice would be extremely helpful.
