Yep Tanya... I have had it with this pregnancy... never with any of my others though.

DH & I DTD unprotected 3 times between 23-24 Dec... and on Xmas night I was sooooooo sick... it hasn't left me yet.
I too got thinking that it might be twins (they're in my family) but who knows... Like you, I certainly hope it doesn't last the whole way through.
Fingers crossed we're both feeling much better real soon
