"hi! so i took ellaone last month and i took it within 10 hours of having unprotected sex. i was convinced everything would be ok until my period was 10 days late! of course i freaked out and was convinced i was pregnant as my period had only ever been up to 3 days late before. took one pregnancy test, came back negative, took another pregnancy test and it was faulty- one line was vertical and one was horizontal (both meant to be vertical if pregnant) so i booked in to see doctor. i had all the symptoms of pregnancy but unfortunately for us women, most of the pregnancy symptoms are the exact same as period symptoms. anyway to cut a long story short- my period came today! ella one does work. it&#039;s just a high dose of hormonas."
