Can I just say that, while it's normal to feel and sometimes be sick during pregnancy, it's entirely possible to feel absolutely fine as well? I've had two pregnancies without so much as a sniff of nausea - it is normal for some!
So given that no-one has any real idea how Meghan is actually feeling, beyond the pulling out of something the other day, she may be feeling just fine.
I have so much sympathy for people who suffer from pg sickness, but I was really worried my first pregnancy wasn't viable because I didn't feel shit. Back in those heady days I think I'd have been grateful for a bit of the gyp!
