Silly question about ttc and 2ww. it cant just be me?

I recently asked what my chances are for being pregnant after having my last AF on January 15th and BDing on the 27th, having a positive OPK on the 28th, and BDing on the 29th using preconcieve...any who. I am in the dreaded 2ww and I cant tell potential twinges from my stomach growling or gas LOL :)!!! Has anyone else beena little confused ansd maybe hopeful that it's twinges when it could be something else. BABY DUST TO ALL. PRAYING FOR A BFP FOR ME AND EVERYBODY ELSE WAITING TO POAS THIS MONTH
