Which side effects are common?
The morning after pill contains similar hormones as your normal contraceptive pill
, just in a higher dose. That way, it can prevent pregnancy even when you have had unprotected sex. Due to the higher dose of hormones, it is more likely to cause noticeable side effects. Some women who take the morning after pill for example experience abdominal pain after taking it. In some cases, the morning after pill also causes nausea, headache or tiredness.
It is also not unusual for women who have recently taken it to experience spotting or bleeding. If the morning after pill makes you vomit, you need to contact your doctor or pharmacist, as you may need to take another one.
