Is it possible after missed period to test positive on an ovulation test and negative on a pregnancy test if you're pregnant?

Is it possible after missed period to test positive on an ovulation test and negative on a pregnancy test if you're pregnant?

Possible: It depends on the sensitivity of the pregnancy test and when it was done after ovulation. Pregnancy tests measure HCG, and the blood and urine levels gradually rise after fertilization. Most over the counter tests on urine are sensitive enough to give a positive test about 2 weeks after ovulation, around the time one would expect a period. Urine concentration also affects test.

I did two pregnancy test one is positive and one negative on the same day. Am i pregnant or not?

Trust the test: Home pregnancy tests are very accurate. They are the same tests used in a doctor's office. They can detect a pregnancy 7-10 days after conception. The best time to take one is when you miss your period. If you doubt the result you can repeat it in 1-2 days. If you were pregnant the hormone level would rise enough for detection. ...Read more

If a at home pregnancy test says negative will the blood test say it too?

If a at home pregnancy test says negative will the blood test say it too?

Likely: Today's home preg tests can pick up very low levels of the preg hormone hcg. I consider those results reliable. If a result is questionable, repeating the test in a few days will be helpful. If there is some concern about the viability of a pregnancy then serial quantitative blood HCG levels would be helpful for diagnosis. ...Read more

Hi if I had a positive pregnancy test  then spotting and a negative blood test of only 3.4 for HCG was I pregnant or not pregnant at all?

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

Can a pregnancy test read positive before implantation?  My period is due on the tenth but test said positive 10 days before next period.

No: A pregnancy test can only read positive after it has implanted into the uterine wall and started to produce HCG (human chrorionic gonadotropin). If it's positive, it's likely that you become pregnant the previous month. ...Read more
