Nausea during 2ww

Options

Advice / Thoughts needed from IUI veterans: 

I had my 1st IUI on March 31 & I am halfway through my 2ww - but in the last couple of days, I've had bouts of nausea just hitting me left & right all day long. I have been trying to eat small amounts throughout the day to alleviate the nausea but it doesn't really subside for long.

My 1st question is: Is this normal?

And of course my 2nd question is: Any tips on nausea relief? 

Thanks,
