Ah, the Yuzpe method, it's basically taking high-dose birth control pills in two doses, 12 hours apart, and it works best kung within 72 hours ka after unprotected sex, so the sooner the better talaga. Maraming kaibigan ko na natry nito at nag-work, pero may side effects talaga like nausea, dizziness, at irregular bleeding, pero temporary lang. Thing is, hindi siya 100% effective, especially kung malapit na ang ovulation mo, kaya importante na usap mo agad ang OB mo para malaman kung right option sya for your situation, lalo na kung breastfeeding ka pa lang.
