Is it normal to start vomiting in last trimester?

I had so much nausea and vomiting until I was about maybe 18 weeks and it went away completely. Now I am at 33 weeks and I am starting to have some nausea and have thrown up twice so far. I hate this feeling and I'm not sure if it is normal...

Completely normal (and pretty common) for morning sickness to return in the third trimester.
Some women have it their entire pregnancy.

Yep. Very normal.

umm not sure but make sure to drink a lot of water so you stay hydrated.

Yep.

My morning sickness came back with a vengeance at the end of pregnancy.

Completely normal. Eat smaller portions so that your stomach doesn't get overly full and make sure to get enough liquids so you don't get dehydrated. Only 7 weeks to go momma you will survive but it just sucks!

I was afraid of that. I have no idea how I am going to survive through work! I hate using public bathrooms where everyone can hear you and how if I need to then I have to run and hope there is an open stall
