17 weeks and still feeling miserable

Jennifer
I'm sure I'm not the only one, but I'll be 17 weeks tomorrow and I still feel pretty awful. With my first, everything got better at 12 weeks but this time around I had a week or so that showed some improvement around 14 weeks but I'm back to having severe nausea at night and I'm still exhausted. Anyone else have a similar experience? I'm really starting to worry it's going to be like this the whole pregnancy.
