See below: If you had a regular period after sex, you are not pregnant. Withdrawal is not a safe way for contraception. 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 if you have sex. Get HPV vaccine

Unlikely: It is unlikely that you are pregnant if you had a normal period however conscientious use of OCP improves their effectiveness.
