I had sex on my period. Could i be pregnant? Important. My period always lasts up to at least 7 days. But after having unprotected sex it only lasted for 3 days. Is this a pregnancy sign?

In brief: Maybe

There is no "safe period".
Pregnancy has been documented from sex on any day of a woman's cycle, including menses. There are better or worse days if your trying to get pregnant, but any unprotected sex can result in pregnancy. If your pregnancy test is negative, consider using BC at all times or it will eventually be positive in the future.
