Missed miscarriage

Just found out that the baby stopped developing at 6 weeks 3 days. Per my LMP I should be 9 weeks 3 days. I'm really sad and don't know what I should do. I opted for the prescription to help the baby pass. I don't think I'm going to try again. We used <a href="https://glowing.com/glow-fertility-program">IUI</a> and I've been through so much already.
