My wife was 7days late on her period she had pregnancy symptoms and then we had sex and her period had came can she be pregnant or no ?

Get a pregnancy test: Since she eventually experienced bleeding it is most likely that in fact the bleeding represents her period (menses). However, whenever in doubt it is best to get a pregnancy test to be certain.

Don’t guess.: Take a test.  they are the same tests used in a doctors 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.
