"i took the pill 12 hours later at night. i was so scared i was going to be pregnant because i could have swore that i ovulated the day before. i felt that mini cramp. i have a period calendar, but my periods have been irregular so i wasn&#039;t sure when i actually ovulated. the next day, i was a little dizzy. i didn&#039;t want to move around as much because i was scared i would throw up. this lasted for 2 days. in the end, i didn&#039;t get pregnant! my cycles are irregular and my last cycle length was 36 days. this one was 29.
