Did throwing up 2 hrs after the pill make it ineffective?

User Profile
I have been taking Tri Sprintec consistently for about 3.5 years with no problems. I took my pill on a full stomach at approximately 11:30 and felt extremely sick to my stomach around 1:30. I threw up a large portion of the meal I had finished around 10:00. After taking today's pill, I only have two pills left in the month before I start my placebo week. Did throwing up 2 hours after after taking the pill make it ineffective? If so, what should I do and will it effect my protection next month?

Welcome to ehealthforum,
Vomiting within 3 hours of taking the birth control pill might cause the pill and its contents making it ineffective. It will be considered as missed pill. You should have considered following missed pill protocol. However, since only 2 active pills are left, you can consider waiting for your periods/withdrawal bleeding during your placebo pill week. Visit your doctor/gynecologist for further evaluation and assistance. Start with your next pill pack at scheduled time.
Take care.
