Hey ladies

I'm 30 weeks and 4 days. Last night went into the labour ward as I didnt feel bub move much all day and felt his movement has changed. 

While there bub was okay but his heart beat sounded strange. They said it could be an arrhythmia or ectopic beats. We have to see a specialist next week to see what it could be. Its been perfectly normal at each visit so muct have developed between my 28 week appointment and now. And now I have to have weekly visits to listen to his heart until I give birth. 

Has anyone else been through this? I'm super worried and stressed for my babe and cant stop thinking of the worst  :(
