Well update scan went well they didn't,see the band/second sac so either she pushed it out of the way or it was banshing twin..I was 29 wks 5 days at scan she measured 29 wks 3 days but she is still small only 2lbs 15 oz which Dr is a,little concerned with so ill have another scan in 4 weeks to check her growth again..and I've hit 20 lbs weight gain yay..oh and Dr told me to count contractions when I have them and if I have 5 or more within an hour I have to call her another reason for a fu scan but my next appt is in 2 wks
