Hi mga sis i'm new here. This is a nice to know info. Nabasa ko lang sa wikihow.com
"Begin taking the pills. You can start any type of birth control pill at any point in your cycle. People often mistakenly believe that women must start their birth control pills at a certain point in their menstrual cycle, such as the first day that they begin their period. Fortunately, this is not the case. However, if you begin taking your first pill pack during the five day time period after you start your period, you will be protected against getting pregnant right away and will not have to use any additional back-up birth control methods. Starting any other time is okay as well, however, you will need to use another form of birth control for approximately one week."
So para po ito sa nagtatanong kung pwede uminom ng pills kahit hindi mo 1st day ng mens. The answer is YES!
