Protein during pregnancy?

Josie • Cosmetologist ✂ Nature lover🌲🌻 NLB♡ Matix Roy💙Sienna Colleen🌸 & baby due May 20th

So I’m not vegan or vegetarian however I’m 15 weeks pregnant and cannot stomach meat. I worry about getting the amount of protein I need and wondering what other ways I can get it? I can maybe do a little tuna, however the Mercury makes me nervous.
