missed pills/ should i take pills as a morning after substitute?

my question is..... I had been out of town and didnt have my birthcontrol pills bc i finished my pack while out of town and then started my period as usual. when i called to refil they told me i was out of re-fils and i was suppost to start my new pack on sunday but i didnt get my new pack until thursday (yesterday). not thinking i had unprotected sex thursday morning (yesterday), got my new pack later that day and i took three pills that night ( sunday, monday, tuesday ) then two this morning ( friday ) and then i took my last pill, the actual friday pill, today (which is friday) at my regular time. i did feel sick today ( nausia, and i was tired ) but it didnt last all day i layed down went to sleep for a few hours and woke up feeling fine

I looked up emergency contraceptive information and it told me that taking 5 pills within 120 hours after having unprotected sex and then taking 5 more pills 12 hours later would basicaly substitute as " the morning after pill"... so my question is since i didnt take all 5 pills at once, i took 3,then 2, then 1.....should i go ahead and finish by taking the last 4 needed to make the correct amount of 10? and if i do will it still work? what are my risks of getting pregnant? what should i do? should i just stop now that im cought up on my days and just start taking my usual one a day/ or take the 4 as a precaution? im confused <img title="Embarassed" src="../includes/tinymce/jscripts/tiny_mce/plugins/emotions/images/smiley-embarassed.gif" height="18" alt="Embarassed" width="18" />
