I am convinced that stress and positive attitude don't make one bit of difference. Afterall, if positive attitude counted, we ALL would have gotten pg on our first try w/DE, when we were so sure that donor egg was the magic key. And I have to say, the only two times I managed to get pg were the times that I was convinced it didn't work, and they were the most stressful cycles. ANd I'm sure I had Thai food and curry, as I love it. Although, I had leftovers for lunch the day of my last transfer, and I immediately threw it up. I say that is the earliest morning sickness ever. ANd it was perfectly fine earlier, so it couldn't have been food poisoning. It was leftovers. I was more worried over the flip flops that my stomach just did, but the nurses said it was fine, and the beta proved it.
And I know plenty of people who travelled across the world (and there are many on this board) who had to lift their suitcases at some point, and it wasn't a problem. As long as you weren't lifting super heavy objects repeatedly, I think you will be just fine. I think someone here posted once that their doctor said to not lift anything heavier than their child (who I think was a year or so).
It's so hard to do, especially without the personal butler, servants, massage therapist and acupuncturist at your beckon call, but try to just take it easy and just enjoy these two weeks of pregnancy and we will all hope and pray with you that it turns into another 8 months or so.
