Relationship after miscarriage

My boyfriend and I have been together for a year and a half. We’ve been through a lot together, including a miscarriage just a few weeks ago. Lately I feel like our relationship isn’t the same anymore and I miss how we were in the beginning. Nothings really wrong in our relationship, aside from some minor issues that I feel are normal in relationships, so it’s not like it’s toxic or anything. I just feel like something is missing from our relationship. Could this be because of our miscarriage? Is this normal? What should I do?
