I had my period about 3 wks ago, 7days after unprotected sex with plan b. can i be pregnant? my period is due in a week. barely any pregnancy symptoms

Unprotected sex: If you had a period after Plan B, it is unlikely that you are pregnant. Your regular period may also be not exactly on time. Taking a pregnancy test a week after the expected period may be reassuring. Please practice safe sex and use an effective form of contraception and protection against STIs/STDs.

Doubtful: Its physiologically not possible to be pregnant if you truly had a period since having intercourse. The catch, of course, is that its sometimes hard to know if your bleeding was a period or bleeding from some other cause . You can be pretty certain, if the bleeding came a the right time and was normal in terms of duration and flow. If you miss your next period, do a pregnancy test. Best wishes
