I have started getting much worse also! I have had morning sickness really badly through this whole pregnancy, it was starting to get better around 22 weeks, to the point that I wasn't nauseated over and above the meds. Once I hit 29-30 weeks it got pretty bad again, and these past few nights I have been waking up in the night, crying to husband about how I feel like I'm going to throw up everywhere. I am hoping that this is a sign too!!
