I had a missed miscarriage four months ago. The baby died at 8 weeks, but we did not know until my first scheduled ultrasound at 13 weeks. It has been devastating, and we have been trying to conceive again for three months with no success. Does anyone know what could be the possible reasons for this? I have been practicing FAM, and know when my peak fertility periods are. The first time we conceived we were pregnant the first time trying, so these months have been particularly confusing for me.
