When does c/p fear go away?

BFP at 10DPO and I wish I hadn't caved and tested.  The first time I waited until I missed my period before testing.  The fact that I'm still nursing and have only had 3 post partum cycles makes me a little nervous about this.

Is there a safety zone that the fear of a chemical pregnancy goes away?  Should I just see if I get my period within the next week and if not I'm clear?  Take another HPT in a week?

Geez you'd think I'd never done this before.
