I had a nasty fall yesterday, landing into a dresser tummy first. Threw my body into contractions 2-3 min apart.. I was at the hospital being monitored.. Baby Wes is fine. They gave me a sedative to help relax my uterus and it slowed my contractions down to one every 6 min..He's not hurt, I'm 29 weeks Friday.. And they sent me home around 11:30 last night with mild contractions and dilated to a 2😞 I've been having contractions throughout the night and they are strong enough to wake me up out of a dead sleep... Should I just keep track of how far apart they are?
