I live in the uae and there are no emergency contraceptives available. My husband and I had an accident (burst condom) which resulted in unprotected sex. I took marvelon as emergency contraceptive - 4 pills, then another 4 12 hours later. After the first set I felt okay until maybe 9-10 hours later when I started to feel a bit of a headache. After the second srt I quickly started feeling sick and having quite sever pain in my rib cage and around my back, almost in a band. I have now been sick and am concerned. Should I go to the doctor?
