so I'm going to be 22 weeks on Sunday and since around 4 something yesterday morning I've been having very sharp pains in the lower left and right side of my stomach. my stomach will become very hard then go back to kind of soft a few minutes later but the pains have been coming a lot more frequently now. and I am having a lot more discharge. I called the nurse at my doctors office and she thinks it might be braxton hicks contractions but it might be something more but she didn't say anything more about it. should I wait it out or go to the er?
