Ah sis, yan talaga ang worry ng maraming ladies dito! Honestly, marami akong kaibigan na nag-take na ng emergency contraceptive, and yung common side effects na nasabi nila ay nausea, dizziness, mild cramping, or irregular bleeding after, pero honestly, it varies talaga sa bawat tao, some walang maramdaman. The sooner you take it after the incident, mas effective siya, kaya if nangyari na, best to see a doctor or go to a clinic agad para ma-advise ka properly kung ano ang right pill for you at may guidance sila on what to expect. Did you manage to get to a clinic na, or are you still planning to?
