Third trimester morning sickness?!!

Rach

I had very bad morning sickness (really all day sickness) and vomiting for the first 18 weeks. Doctor put me on diclegis to help. Was really enjoying not throwing up and feeling nauseous all day for the remainder of the second trimester. And now it feels like it’s coming back!

Have been nauseous all week and threw up everything I ate last night before I went to be. Has anyone else experienced this? Is it normal?
