Feeling ill constantly

Stephanie
I've managed to finally reach 31 weeks and I'm still struggling to cope. I've suffering severe sickness, acid reflux, heart burn and now I'm just exhausted, feel groggy everyday and generally can't cope. 
I'm getting through by thinking only 9 weeks left but I have this awful fear this feeling of everyday living like this won't go? 
Will this disappear after the birth?
