Birth Control/vomited after pill.. what to do?


I took my pill at my normal time at 11pm, however at 3am on Saturday morning I got gastro so I started vomiting and had severe diarrhoea. Instead of waiting until 11pm on Saturday evening, like I normally would I took one at 3pm. I have been on the active pills for a while as I skipped my last period, and I still have 2 more weeks of active pills to go. I did however have safe sex only a few hours before taking my pill on Friday at 11pm (the one I vomited up).  

I want to start taking my pills back in the evening so what should I do? I also want to know what's best for me so that I am still protected against pregnancy (however I always use a condom regardless)... I was thinking I could take my pill today (Sunday) at 5pm, then 7pm the next 2 days and then 9/10 the day after. Does this sound ok or what do you recommend? When is it ok for me to start having sex again?


If you are using condoms and they do not break or come off, then you will not get pregnant.

In terms of the pill, you can start taking them whenever you want and as long as they are the kind with both estrogen and progesterone then you could just start taking them at 11pm again as a few hours won't make a difference.

I hope this helps,

Birth Control

I can answer questions about how to choose which method of contraception is right for you, how to deal with mistakes, effectiveness, and emergency contraception. I also have training in HIV, STIs, and sexual health education. I cannot tell you what is the right choice, but I can tell you the pros and cons of each method to help you make an informed decision for your circumstances. If you have had a condom break or had unprotected sex and need emergency contraception please call you local Planned Parenthood or check out
