This is my first time taking any form of birth control. My last period began on 3/27 and my next one isn't expected until the 26th or so of this month, but I'd like to start taking the pills right away. I asked my doctor if I could start tonight (4/9) and she said it would be fine... but in reading the directions included in my prescription, it says to start either within the first 24 hours of the first day of your period or on the first Sunday after your period begins. So is it still fine to begin them tonight? What should I expect? And will I still be protected this time next week?
