Congrats, Gumb69! No, changing your ticker won't make you miscarry, but I know the feeling. I'm holding off on painting my nursery and buying anything for the next 10 days as that's when I'll get the my chromosomal results... I feel like if I buy any thing now then the chance my baby has a horrible chromosomal defect that makes him/her not viable will be higher. Ridiculous and non-scientific, I know! Buying stuff or otherwise preparing won't affect this pregnancy, but that feeling it will is still there!
