I have been on Yasmin for 7 years but missed the last two pills on my third week of the pack. During sex the condom broke and now I am worried that even though I am on the pill, I may need the Plan B pill. I am going to start my new pack of birth control today. Please let me know what my chances are of being pregnant and if I should take Plan B with my birth control or if I could possibly be alright with just my pills.
