When to start shopping?

Ca
I feel like I jinxed myself last time and bought a few items during week 5 then had a MC. I'm at 5 weeks now, bloodwork looks great! Pee sticks are now pulling from the control line, my cb digital rose to 2-3 weeks (last time that's how I knew I was going to mc, because it wouldn't go above 1-2 weeks). The real question is: when do I actually start to buy things? What do I start with? I really want to start shopping but am having a hard time waiting until my ultrasound on Feb 17th!! Help!!
