NST some concerns.....

Today I had my scheduled NST Test.  The nurse noticed that Liam's heartbeat would pause slightly in between beats.  She asked me if anyone had noticed this before and I told her no. She asked if I was anemic and I said no. She said this happens sometime to mothers who are anemic and it may not be anything to worry about it may go away tonight but she wanted to be sure to let the doctor know.  The monitoring for the NST test was fine. All my tests were normal Liam was moving and his heart beat was increasing at the right times etc. The actual NST Test only took an hour today which was good.   The nurse said the doctor wanted me to check in with her on Monday just to be sure.  Please keep Liam and I in your prayers.
