Yes, likely u will: Like most long term medications, the effect takes time and typically requires multiple dose before attaining a steady level for therapeutic effect. Since your menstrual cycle is hormonally regulated, starting ocp on first day of your cycle likely won't affect the current flow at all. But like all med, unexpected reaction can occur and so if you have trouble, consult doc. Good luck.

Starting birth contr: I was trained that you started oral contraception on the Sunday after the start of your menses or period - thus you would not tend to get your period on a weekend. Ideally you would start on the first day to assure yourself you aren't pregnant. Also starting then eliminates the possiblity of hormonal overlap with your bodies levels. where in the cycle are you?

Extra bleeding: Assuming you are not pregnant, starting your birth-control without waiting for your period won't hurt you; but it can make you have irregular bleeding or extra periods for a few months until your body adjusts. Its best to wait for your period so that you know you are not pregnant and the pill is in sync with your natural cycle. Best wishes!
