Miscarriage grief hitting at due date


My husband and I did <a href="https://glowing.com/glow-fertility-program">IVF</a> in February. Got pregnant from our first transfer in March. We were so excited. We waited so long for this and It finally was our time. My HCG numbers were great. We went for our first ultrasound at 6.5 weeks. They saw a gestational sac but nothing else. Waited a week and went back for another scan. Still not baby. So the baby stopped developing very early. We were devastated. I felt like I grieve and then just wanted to move on to the next step. Well my baby was supposed to be due 11/21 and I’ve been severely depressed. My therapist believes I never grieved and it’s all coming out now. I’m really really bad 😢 has anyone experienced this with grief?
