"back story, i was on the mirena for 5 years and got off of it in early 2017 (my body has already been used to the hormone in the morning after pill) i had taken the morning after pill about 16 hours after unprotected sex with someone i didn&#039;t know. the last 2 weeks of my life have been horrible. i had no initial symptoms of the pill until about a week after taking it. i track my periods using eve. and it was during my most fertile day that i had sex. which made me panic 10 times more. i felt sick 24-7. i even threw up. my period came 2 days late. and i&#039;m still on it. it&#039;s much lighter than i&#039;m used to and the cramps are horrible. the moral of the story is. don&#039;t panic. listen to your body. every thing will be fine. the pill did work."
