Hi, Anon.

Thank you for your post.

Emergency contraceptives are up to 95% effective when taken as prescribed within the first 24 hours, so the risk is very small. Side effects can include stomach aches, headaches, nausea and a general feeling of being unwell. Symptoms usually start 3-7 days after taking the medication and may or may not include bleeding or spotting. Not all women get symptoms. Some get many or a few or none. If you don’t get your period within a week of its expected date a pregnancy test may be necessary although the risk is low. It can cause an early period or a late one. You may have a lighter or heavier flow, so be aware of this.

ECP should only be used in emergencies and not used as a regular form of birth control.
