I’m 14 weeks, 5 days. I stopped my Unisom and b6 2 days ago thinking surely I was past the nausea by now. I threw up for the first time today. Looks like I’ll be back on Unisom/b6 for at least a few more weeks until I’m brave enough to try to go off it again. To top it off I’ve had a horrible headache today that Tylenol won’t touch. Maybe the headache caused the vomiting. I don’t know. I’m just ready to be past this stage. Last pregnancy it lasted until 16 weeks.
