I have been on yasmin for a couple of years now. I had unprotected sex during the first month of using it and i was perfectly fine. I wouldnt be too worried unless you dont get your period when you are suppose to, a couple or several days after you take your last active pill. You will most likely be fine but take precaution next time so you wont have to worry about it
Because your body has to adjust to being on the new pills. Also birth control pills are not 100% affective too. TO be on the safe side, most use bc pills and condoms (or another non hormone).
Thanks for your advice. How come you should use another form of protection in during the first 3 months?
I would suggest to wait and see if your period comes on. You should be using another form of protection when using bc pills ESPECIALY in the first 3 months of starting them. You could take plan B but it might alter the affects of your bc pills seeing that u only recently started them. Maybe somebody else has better advice.
