Quinoa is a good source of protein, if you don't know what it is - it's kind of like cous cous. I love it!
Also, beans (soya, mung, butter, kidney etc) are a great source as are nuts!
There are loads of ways to get protein without red meat babe!

Could you also find a pregnancy friendly protein shake? I'm sure there are a few on the market at the moment, health food shops might be able to help you out.
