hi, i wanna ask,, my period last month was sept, 21 and i m taking postinor 2 at oct, 5th after at oct, 4th sexual intercourse without a condom (less than 24 hours). and at oct, 12, i had sexual intercourse again, but the condom loose and i had spotting just like early menstruation. because i was affraid, i take postinor 2 again at night. today, spotting still seen, but its brown, different with yesterday, its red. i wanna ask : 1. is it safe to use postinor 2 twice in 1 week different time? 2. is taking postinor 2 after i know i had spotting, influence the spotting? 3. is the spotting caused by taking postinor 2 at oct, 5th? if isn,t, what cause spotting? 4. how accurate the postinor 2 at me after you read my history? thank you so much
