What weeks are pregnancy tests most accurate after conception?

3 weeks after sex: A urine pregnancy test done correctly gives a reliable result 3 weeks after sex (3 weeks after when conception might have happened) 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 therefore lead to a repeat test. If a woman has her normal regular period, then she is not pregnant, and a test is not needed. ...Read more

Maybe 10 days: A good rule of thumb is that the beta is about 100 on the day of missed menses which is 14 days after ovulation. If the beta doubles every 2 days or so then working backward gives you a beta of 25 on day 10 after ovulating. ...Read more

What is the point of conception indicators on urine pregnancy tests when they are deemed inaccurate?

What is the point of conception indicators on urine pregnancy tests when they are deemed inaccurate?

Depends: For some women they do not work well and so using them is a waster of time. For some women they are very reliable but not perfect. In general they are overrated, if it is just to time sex then it is better just to have sex more often around the time you think you will ovulate. If they are used to time fertility treatments, often the doctor will have backup plan in case the kit in not working. ...Read more

Are early response home pregnancy tests accurate 10-14 days after sex? I'm on the pill and my period isn't due until 4 weeks after the sex in question

Maybe. Maybe not.: A urine pregnancy test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred). 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. It's best to be patient and not test too early. ...Read more

Periods 6 days late... 2 negative pregnancy tests. Periods are never late, only come early sometimes. Should I test again? Could I still be pregnant??

Periods 6 days late... 2 negative pregnancy tests. Periods are never late, only come early sometimes. Should I test again? Could I still be pregnant??

Ovulation: If your periods come early sometimes, they may also come late. The most common reason is that you aren't ovulating every month resulting in irregular bleeding. I would get a blood pregnancy test to be certain and speak with your physician about doing some testing for irregular ovulation and maybe start a birth control pill. ...Read more
