So worried

Chantel • Had my micro premi in 2013 at 24 weeks and a loss 06/09/2016 praying for my rainbow baby 🌈🌈🌈👶🏽🙏🏾🙏🏾🙏🏾🙏🏾❤❤❤

So had a ultrasound at 6 weeks 1 day to check for heartbeats and both babies were only a day apart in size but had a ultrasound on Friday 10/20/2017 and babies at measuring 1 week apart and baby A heartbeat was slower than baby B is this normal or is this just being paranoid had a rough time TTC and am high risk before multiples are added in the equation
