The only pre-bfp sign I had when I was KU with DD was cramps around my AF due date. Now every month I get cramps and think I could either be really happy I'm getting them or "damn, I hate cramps" cramps. Yeah, extra annoying.
I just hate that pregnancy symptoms are pretty much the same as period symptoms. The only major difference I noticed? When I was pregnant, I had really crazy dreams a day or two before BFP.
With my one pregnancy I didn't have time to pay attention to other possible symptoms because I was a bit distracted by our house having been burglarized. After discovering the break in I figured the cramps were PMS so it gave me the chance to down a "dammit, our house got robbed" beer. Two days later we found out we were pregnant.
