Missed 3 periods, negatives pregnancy test. Hyperthyroidism not currently on medications. Can hyperthyroidism cause a false negative, or stop ovulation?

I don't think there is anything specific about hyperthyroidism that would cause a false negative pregnancy test; typically an error in testing (imprecise following of directions) is to blame. Work with your doctor to optimize thyroid function. ...Read more

Is it possible to get a false negative on a pregnancy test taken two weeks after conception?

Is it possible to get a false negative on a pregnancy test taken two weeks after conception?

Yes, sometimes: A urine pregnancy test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test. If a woman gets her normal regular period, then she is not pregnant, and a test is not needed. ...Read more

That being said, a false negative pregnancy test is rare after 4-5 weeks of pregnancy... which means that if a woman has not "confirmed a pregnancy" at 16 weeks, and she gets a negative test result, she should visit her doctor. ...Read more
