Oh good grief- don't be embarrassed by that. Seriously, my friends and I have a long standing joke about our paranoia of getting pregnant (I can't tell you the specifics of the joke, it would probably offend some people). Trust me- I bet the majority of people who buy those tests are NOT pregnant, and if you can sleep well at night, what does it matter? If it makes you feel better, the last time I freaked out I bought a two-pack so I'd have one on hand the next time I panicked!
