Im currently in my 3rd week of my second pill pack. this morning i discovered i was on a monday pill instead of today (a tuesday pill). im not sure how i got backed up because i remember taking a pill the day before. so within the past 2 days i missed a pill, but continued with the next pill the next day. now that i realized this, i took 2 pills on tuesday. will this have any affect on me ? today i had some bright red blood, I assume from taking both pills. any advice ?
