If you are late in taking your mercilon oral contraceptive pills, there is always the chance of you getting pregnant, especially if you had recent sexual intercourse. Forgetting to take oral contraceptive pills on time is one of the most common reasons for pill failure. In order to prevent unwanted pregnancies, it is best to see your gynaecologist who can then recommend emergency contraception if you have had intercourse within 5 days of not taking your mercilon pills on time. The 2 recommended forms of emergency contraception are :
1. IUCD (intrauterine contraceptive device, which should be effective for 5 years)
2. Ella (1 hormone tablet)
For Ella, as it is high dose hormones, should you vomit this out, you will need to return for another dose or else it will not be as effective as it can be.
