Hiya mummytogirls, I also found the bits of the pregnancy that I had done loads of times before really hard to enjoy. I couldn't get excited, or even think about the fact that I was pg. Couldn't join a belly buddy group, post on PAML thread or even in my blog. I just had to remove myself from everything. But as we got to a part of the pg that we'd never been through before, it got more exciting and I felt like I had passed my milestones. Maybe you will feel like that at 20 weeks?
