Stillborn?

Has anyone ever experienced a stillborn birth? I had my baby at 31.5 weeks. I was at a routine check up and they couldn't find his heart beat 😔. TTC now since this happened and it's been almost 8 months. 4 months after the lost I got pregnant but only to find out it would end in a early MC. I'm feeling so low at this point. Maybe because I got AF this morning? I just needed to vent. I feel like no one understands me. My heart has a hole in it that cannot be filled. No one I know can relate and makes it difficult to talk about. I'm hoping to find some support here. Thanks for reading.
