I had unprotected sex 9 days before my period could i be pregnant

Possible: Pregnancy is know to have occurred from sex on any and all days of the cycle. If you had sex within the last 72 hours and you do not wish to be pregnant, you may take plan B. If you miss your period by 4-5 days, do a home pregnancy test. If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex. Get HPV vaccine.
