FTM here w/Braxton hicks at 32 weeks. My stomachs been tight most of the past hour but she's super moving. My md last week said if I have more than 4 in an hour to call her to make sure im not having prelabor. But they're not bad so I know it's not "real" contractions. So I haven't been timing it or tracking it. Just drinking lots of water and walking around. Should I call to be safe???
