Hi Doctor. Me And My Gf Had Unprotected Sex And

Hi Doctor. Me and my gf had unprotected sex and used withdrawal method. Just to be sure, we bought Nordette and she took 4 pills after 40 hours of unprotected sex and then another 4 pills after 12 hours. After 5 hours of second dose, she vomited, but very very little (like 5ml) please help us as we are using Nordette for first time and are hoping for good results. Thank you and good day
