"had unprotected sex around 11pm and took the pill at 10am the next day. i live in the uk so i got it for free from the local nhs walk-in centre. after taking the pill i experienced some depression, apathy and was sleepy for the next 4-5 days to the point where i would sleep for 13 hours and still feel tired. 5 days after taking the pill i experienced light spotting. i also felt nauseous from time to time 2-3 weeks after. got my period 6 days late. was totally freaking out before that so did home pregnancy tests and went to see my gp. he said it&#039;s normal to have delayed menstruation or even skip a month after taking the pill. do a home pregnancy test if you&#039;re anxious.they are 99% accurate if taken 3 weeks after last unprotected sex."
