"i was reading the reviews the other day and i was very nervous on whether it would work for me! i had unprotected sex back in mid september (a drunken foolish decision) and nipped to the chemist the following morning to get the map. i was in the middle of my ovulation window. i took it within the 1st 12 hr window so was assured by the chemist i had the best chance of it working and thought little more of it. i track my period using an app on my phone so when i was due i got notification. 4 days later and still nothing. my head started to go crazy so i took a test and it said negative which made me relax a little but when i still didn&#039;t get my period i was stressing. this morning it finally arrived 18 days late. i&#039;ve never been so happy."
