How much time after a missed period can you be sure that a negative pregnancy test is really negative?

Should be positive: Usually takes about 14 days to turn the pregnancy test positive. That means if you ovulate in mid cycle, by the time your period is supposed to happen, you should be positive. Supposing you ovulated in late cycle, you could perhaps see it 2 weeks after your missed period.

One week : Home urine pregnancy tests are sensitive especially if done on the first morning urine. If the specimen is collected later in day, urine more diluted and can be a false negative. Can usually see a positive by third day after missed period. To be safe I'd recheck at one week.

Anovulation: It sounds as if you've experienced an anovulatory cycle. These are cycles in which the ovary failes to release the egg. This disrupts normal hormonal levels.

Time to see doctor: Menstrual irregularities are not uncommon and anovulatory cycle is a common cause. Since you missed more than two periods it is be time to see your doctor. If you do not wish to be pregnant, use contraception all the time. You may consider implanted contraceptive or an IUD.
