PSP, try not to worry so much. My doctor also say he will only be happy with my progress and give me a thumbs up after 1st trimester.
Like the ladies said, just continue to do what you can and what is within your control such as have enough rest, take support medicine, eat healthy and think positive. Our bodies work in mysterious ways and trust that everything will be fine. When I went for my scan at 7w+2d, my baby was only 10mm which is only 1 cm! So small and all I could see was a glob. And I was thinking how can something so small make me so bloated and so sick!?! Incredible! Ha ha!
