"just something quick to help anyone that&#039;s worrying. i took ella one, 30 hours after unprotected sex. my period was due 2 weeks later making this a very fertile time. my period didn&#039;t come had cramps, morning sickness and tireness. which made me even more worried. did so many pregnancy test all were negative. got my period today 7 days later. so relieved. the symptoms i thought was pregnancy must have been worry and stress. the morning sickness i think was me waking up and taking tests and getting myself into a state. hope this helps someone."
