Re: negative hpt, when should I test again?
Even though they say "anytime- you don't have to use first morning urine" I think the hormone concentrations are higher in first morning urine. Whatever day you decide on, I would take the test first thing in the morning.
Can you pinpoint when the intercourse was that could have caused the pregnancy? If you know that date that you were "irresponsible" (don't be too hard on yourself- almost everyone has been there), testing 14 days after that intercourse should give you definitive results, especially if you use a good "early response" type test. If you don't know, just wait another 7 days and see what happens.
I hope you get the answer you are looking for. Waiting to test, whether you're hoping for a positive or negative, is one of the worst feelings. Keep us posted.
