Will taking my birth control pill straight after I've had unprotected sex protect me?

No. Yes you could take birth contorl after unprotected sex but it will not work. Birth Control prevents ovulation, once ovulation happens birth contorl would have no effect on the potential for fertilization and implantation.
Not always. hen is your next cycle? If you are have unprotected sex during your ovulation period, OCP may fail.

Likely safe. 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. Read more...
