:( maybe it's a bug. Have you gotten your flu shot? Its "winter" time now... And us being pregnant, we're a little more prone to get sickies. Feel better momma.
I am also 30 weeks and feel sick after eating. I have to eat slowly and take breaks between my meal. I guess it helps digest. This has helped me, and maybe will help you too? Im sorry if this isnt very helpful. Just sharing what has helped me.
