I dont feel a connection to my secons child

The title pretty much says it all. My first one i was over the moon about i couldnt stop thinking about him i looked forward to all the dr appointment i loved listening to his heart beat and i looked forward to every step of the whole gestational period. But with this one i dread the whole thing and i feel no connection to it... it's like i have the flu instead of being pregnant im just afraid the connection will never happen. I've seen where other mothers had the same issue but once they saw their baby they fell in love. I hope thats my case.
