Loestrin/Missed Period

I am on my 2 pack of Loestrin 24Fe.  I've never taken this before and I was on Trivora for quite awhile.  Last month I got my period over a three day period (Wed-Fri).  It is now Friday (of following month) and I haven't gotten my period yet.  I have had VERY SLIGHT spotting however.  I'm 34 years old if that helps.

ok, most likely, as this is a new form of birth control for you, it is upsetting your cycles. however, you might have experienced implantation and the birth control has failed. unlikely, but possible, it does happen. i advise testing on the day your period is due with a first response test.
