Ovulation with Letrozole

Melinda

So this may be a stupid question but My husband and I were recently put into the unexplained fertility category. I started letrozole this month and with an ultrasound showed two follicles, one on each side. My question is, if I released two eggs during ovulation and one egg was fertilized and the other was not, does your body still discard the unfertilized egg resulting in a period? Just started thinking about this recently. Thanks!
