Some people have their period every 28 days like clockwork. But most people will experience a late or missed period at least once without being pregnant, and that's perfectly normal.
How many days late can a period be before worrying about pregnancy:-
Everyone’s cycle is different, but how late can a period be? Healthy cycles can range in length from 21 to 35 days, and how long a cycle lasts can vary from cycle to cycle. Unless you have irregular cycles due to a medical condition, you probably have at least a rough idea of when to expect your next period.
A period is considered late if it hasn’t started within seven days of when you expect it. Most pregnancy tests will be able to give you accurate results by the time your period is late. If you get a negative pregnancy test after missing a period, and your period is more than a week late, you may want to see your health care provider to figure out what’s going on.
If you get a negative pregnancy test result, still haven’t gotten your period, and start to experience early pregnancy symptoms, consider taking another test. Sometimes, home pregnancy tests can give a false-negative result if it’s taken too early in the pregnancy to detect human chorionic gonadotropin (hCG) in your urine. In these cases, it can take a bit longer to know you’re pregnant after a late period. The earliest hCG detection can be done with an hCG serum test performed by a doctor as early as 8 to 10 days after ovulation.
Can you be 2 weeks late and not be pregnant?
