Congrats on your pregnancy and welcome to BellyBelly. I agree, dont worry about the appointment until you get back to Aus. As for the sledding, I know its not the same, but I went snow boarding when I was 9 weeks pg with my 1st. I just took it easy and made sure if I was going to fall I would fall not on my tummy. I have also been 4wding when I was 6 months pregnant. Thats probably similar to your sledding. It was really bumpy, I wish I had a pillow for comfort and a toilet...or extra pads! Your little one is deep inside your pelvis at the moment so it should be fairly well protected.

Good luck and happy moving

Melissa
