nausea getting worse?

LT
10 weeks 4 days. Have had some regular nausea since the beginning. But basically since week 10 started,  the nausea is almost non-stop. No puking, but it's all day and evening, with barely a break here and there. Even wakes me at night. Anyone else have this happen? I have a doc appt on Friday, so I will be talking to him about it.
