The pill

Ariel • 20, small town girl
I've been on the pill for almost a year now, and this past week was the odd colored pills for my period. I haven't gotten my period this whole week, i contacted my doctor and she said its okay to miss a period because my body is getting used to the pill. My boyfriend and I are concered because being both full time college students and working part time is no way we'd be able to afford a baby right now. Is my doctor wrong? I feel like it isnt right?
