How can you tell if a girl is pregnant based on her period?

There is nothing one can determine from a period that would indicate being pg or not being pg.





Shelley|||If her period is more than a week late or she had a very very light period for only a day or two then it's time to take a test.|||If she misses her period, she may be pregnant.





Of course, women may miss a period for a variety of reasons- stress, diet, exercise, hormone changes, etc.





And some women may "bleed" like a period, even if they're pregnant.





So, if she misses a period, suggest a home pregnancy test.
