i had my period on the 17th of december and it ended on the 23rd of december. i and my bf had sex on the 26th of december and i took in one dose of postinor-2 and at midnight that day we had another sex and i took in the other dose. On the 27th of december we had sex again and i took in one dose of postinor-2 and this time i forgot to take the other/remaining dose. IS THERE ANY CHANCE OF OF GETTING PREGNANT.
