Plan B And Urination Plan B Sickness Or Pregnancy?

Plan b sickness or pregnancy? - plan b and urination

My girlfriend and I had unprotected sex (stupid I know) 13. November, Thursday, and took Plan B after 23 hours, 14 November Friday. Lately, he has had headaches and cramps, but today (20 November) that finally their rules. She complained to me about back pain, urine constantly, headaches, and hand the need for themselves. It was not able to eat all day because the smell and taste make him vomit. Can anyone tell me what's going on?
