Rifka
I had my last periods on the 2nd of October . My hubby was abroad, so non sex. But he surprisingly came home on the 17th, and we did have unprotected sex that night. And I started the pill Yasmin on the 18th and also took postinor pill. And I'm due for my periods yesterday and still no signs. Should I be worried. Please help
