Suddenly widowed

So me and my husband have been trying for a baby for about 6 months and finally got our positive! We were both so excited that we told our parents immediately (even though people say you should wait). Our parents were beyond thrilled to be grandparents. The horrible part comes when my husband dies suddenly and unexpectedly. So I know find myself pregnant and widowed. I’m grieving my husband while also trying to figure how to manage everything and terrified that the stress and still being early in the pregnancy will lead to a miscarriage. Does anyone have any experience with being pregnant and widowed? There aren’t a lot of supports focused on this particular challenge.
