I missed 14 active pills had light period on 16th day of cycle& now spotting, neg hpt 1 week ago could I be pregnant or light period from missed pills?

Probably not pregnan. Missing pills can cause your cycle to be irregular with irregular bleeding. If you have not been using condoms, try repeating your pregnancy test and if negative, you are probably not pregnant. Try not to miss pills in the future to avoid bleeding issues. If you have resumed taking your pills, then your cycles should return to normal within a pack or two..
