I had sex with a guy and he precummed in me and told me to take advil (ibuprofen) to kill it. is that true or should i buy the morning after pill?

Advil (ibuprofen)?: The manufacturer may claim it is a miracle drug, but this is definitely NOT something it can handle. Get the morning after pill and be safe.

Morning after pill: Ibuprofen does not kill sperm.Ideally morning after should be taken Within 72 hours Of having sex. Please see your pharmacist for the prescription

No: Ibuprofen is a pain killer and will not affect whether you get pregnant or a sexually transmitted disease. Yes, you should get the morning after pill but you should also consider going to a sexual health clinic to get tested for STDs. The only protection against chlamydia, gonorrhoea, HIV, Herpes etc is barrier contraception (condoms).
