If the condom broke but your period started 5 days later could you still be pregnant?

Not likely. Starting your period is an indication that you are not pregnant. However, some women's periods continue (usually lightly) in the early stages of pregnancy. It is not something to be too concerned about, though, this is rather rare. Try a pregnancy test, most over the counter ones are fairly accurate and can be done 5 weeks after the possible conception has taken place.
