Brief Answer:
Vary form your cycle

Detailed Answer:
Hi dear and thanks for your query.

1.If your cycle is of 28 to 30 days or longer and your cycles are regular, it is fairly safe to say that your ovulation occurred between Day 11 and Day 21. The egg is only available for 12 to 24 hours for conception.

This would mean that the days right before your period are the safest for having sex without the expectation of getting pregnant. The number of “safe days” right before your period go up with longer cycles and lessen with shorter cycles.
Hence chances are very small ,almost zero.

2.If your cycle is shorter, for example every 21 to 24 days, this means you are ovulating earlier in the cycle. Sperm can live inside you for 2, 3 and up to 5 days.
Hence chances are there .

Hence ,if your cycles are regular and 28 to 30 days ,there is no need to use any emergency contraception like Marvelon tablets.
If your cycle is every 21 to 24 days than you can use Marvelon tablets .

Marvelon, it is not an emergency pill but can be used for that purpose when no other alternative pill is available.
You will take 4 pills within first 24hrs of sex and next 4 pills after 12 hrs as per your doctor's suggestion. It will give more than 95% protection additionally against unwanted pregnancy.

God bless you
