Hi,
I'm just over 4 weeks pregnant (I think), I took the test yesterday morning, the day after my missed period, and then took another test in the afternoon and they were both positive.
I went to the doctor's (I happened to have an appointment booked anyway for something unrelated and thought I may as well mention the pregnancy then rather than book a separate appointment) and he said that even at the time of a missed period, pregnancy tests aren't that accurate and that even though I had two positive results I should still wait 2 more weeks and then test again.
Obviously I'm aware of the risk of an early miscarriage, and that that would cause positive then negative test results but that's not what he meant, he meant that I might not even be pregnant at the moment. Is that right?? I'd always been under the impression that a positive test was pretty unlikely to be wrong.
