Hey, my girlfriend took 2 postinor pills all at once(pharmacist said it was ok) after 14 hours of unprotected sex. Now the second day she is experiencing back pain, sore waist, she thinks her breast is bigger(not sure), there are a lot of bubbles in her urine and she has stomach cramps at the lower abdomen. Is this normal? Please help. And this morning she took a pregnancy test and it was a negative. And can she take panadol or any painkiller drugs?
