I had unprotected sex (27 sept night). Took 2 yaz pills next day(29 sept morn). But found out 4 had to be taken. So took 4 the day after(30 sept morn). Should I take 4 more after 12 hrs? Where i live, emergency contraceptive pills are not allowed. If ovulation had taken place before I took yaz pills will they still prevent pregnancy? Plz answer..
