question: I take Ortho Tri Cyclen and have for almost ten years.  I'm 31 years of age.  I started a new pack this past Sunday, September 8.  I also took the Monday pill.  I misplaced my pill pack (and honestly forgot about them) until yesterday, Friday, September 13.  I missed four pills from the first week.  My husband and I had intercourse on Sunday, September 8, the first day of the new pack of pills.  I took two pills last night and two today to get caught up.  Today, I had some very minor pinkish spotting.  I'm wondering if there's a chance I may have conceived.  We had sex five days ago.  My period isn't to start for another two weeks.  Do I need to use a back up method for the rest of the month?  How early can I take a pregnancy test?  Do I have to wait until I miss my period?  Thanks for your time.
