A member asked:

How long does it take for the bcp natazia (estradiol valerate and dienogest) to be effective? i started it on the first day of my period.

Right away: You should be protected right from the beginning. You will be more likely to have irregular spotting the first 2 or 3 cycles but as long as you are taking your pill consistently and regularly you will still be protected.
