Meat aversion & taking protein supplements

Windy • 28. Proud mother of 2.
I've always been a meat eater, however I cannot stand meat while I'm pregnant. I read it has something to do with my body not producing enough hydrochloric acid..? anyways I'm 20 weeks and I thought by now the aversion would be gone but it's not. What protein supplement do you recommend? I have Whey protein powder, should I take that or something else?
