So I am on the third week of my birth control pills(combination ones). On Sunday I took the pill about 5 hours late but took the rest of them at the right time until today (4 days later) I took another one 7 hours late. I currently have no spotting or bleeding. So my question is do I have to use a back up birth control method for the next 7 days or am I still protected , because both pill that were missed were on week 3 , but they weren't missed consecutively.
