Hi I took nordette as an emergency contraceptive. i took 4 pills of the pack for the first dose, followed by another 4 pills for the second dose. However, 2 hours later, I feel nauseated and vomited, mostly liquid. I have read that if you vomited within 4 hours of taking the pills, it will not be fully absorbed. What is the chance of me getting pregnant? And do I need to take another pills for replacement? thanks
