Great news on the heart beat! Hooray! And I have no advice for the nausea. I didn't take zofran (In retrospect I wish I would have tried it) but I tried everything else - B6 (which may have helped but since I was taking it before I got pregnant, I couldn't tell for sure), wristbands, ginger . . . the only thing that really helped me at all was a mix of sprite and OJ, but only do that if you want to gain, like, 15 pounds in your first trimester
Again, wonderful news on the heartbeat!
