(1) ALL women are protected AFTER 7 days after starting oral contraceptive pills, no matter when in a cycle they start.
(2) Use of a backup plan for 7 days is recommended if pills are started beyond the 5th day of the start of a period
(3) If you start pills early in your cycle (within 5 days of the start of a period) you are protected immediately, however this won't apply to those who don't have predictable regular cycles or those who don't follow their regular cycles closely...in which case point #4 should be followed.
(4) If any woman is in any doubt, she should use a backup contraceptive for those first 7 days of taking birth control pills.

I seem to remember that the 1st month my wife was on the pill her doctor told us to use a condom as well when having sex as it takes time for the medication to build up in her system. Based on that advice I would say if you were fertile at the time you had unprotected sex you may be pregnant.
You could speak to your pharmacists about taking the plan B pill or try contacting your doctor to ask this question. THe sooner you take the plan B pill the more effective it is. It has been known to be effective up to 7 days after intercourse but is most effective within 72 hours. [ adviceman49's advice column | Ask adviceman49 A Question ]
