Hello Mrs,
I would like to reassure you that the bleeding period when you are taking a contraceptive is in no way useful to your health or fertility. The contraceptive prevents ovulation (among other things), so the bleeding you experience during the placebo pill period is withdrawal bleeding, not a period. On the other hand, if you have just started the contraceptive, i.e. less than 6 months ago, your body may need to adjust, and not having any bleeding, or light bleeding, is completely normal.
Finally, if you are prone to forgetfulness, so that you do not take your contraceptive at the same time every day, I suggest combining it with an activity (such as brushing your teeth in the morning or evening), leaving the pack next to your bed, or setting an alarm on your phone.
In order for your contraceptive to remain effective, I encourage you to continue taking your pills as scheduled.
I hope I have reassured you, and I remain available if you have any further questions
Tom Samaha, pharmacist
