I'm usually very good about taking birth control pills. I travel alot and thus keep an exta pack in my suitcase just in case . This past week i left for vacation on Tuesday- I took my pull Tuesday, Wed, thurs, and Friday from my travel "pack" - Friday was my last active pill for the month. when I got home on Saturday, I noticed I did NOT take a pill on the Monday night before I left. Since I Didn't realize it, i Never doubled up. I did have sex while on vacation without using another method. Should I be worried about pregnancy? What do I do about the missed pill at this point...or just take inactive ones as scheduled and start next pack when I usually would? Thanks
