Hi I take birth control pills and I did have my period last month but I ordered my birth control during the week but I had to wait until Sunday t take it.. so I started my birth control a week late after my period... I took my last pill last Monday night... and it is now going to be Tuesday and I still do not have my period... do you think my perid is just late and off track because of me taking my pills late... or do you think I am pregnant...
