I took a blood test 7 weeks and 2 days after the last day i had sex. i've had 2 periods since that day--one was unusually light, but the other one was pretty normal. i was just concerned about my unusual period. i also didn't feel well during that time--but the symptoms went away after taking medicine for a slight uti. so the answer i received from the blood test (-) is undoubtedly correct now, right? i heard blood tests are better than hpts anyways, and they can pick up the hormone earlier. i know some people still get false negatives from blood tests, but only because they tested too early, so i can be secure with my result since it's been 7 weeks, right? like...i'd be 9 weeks along by now, and i haven't had any other symptoms.
