Help! I have been taking Haley fe 1/20 for about two years now, and I have been doing extended cycles. I will schedule a break week about once every three months. I’m on my last pack right now and I am on the last week before my break week. But I’m experiencing nipple tenderness, and at the beginning of this pack I had a day of light spotting. I have never missed any pills or been late to take them. Is there a chance my contraceptive could’ve failed?
