Please help

Its 6 in the morning and I was woken up by a nightmare so vivid that it scares me. Its been repeating night after night now around the same time but Idk what it means...

The dream starts with me being 7 or so months pregnant, I'm at home waiting for my husband to come home. When out of no where I have a sudden wave of depression cover my body (I suffer from depression, anxiety, and more). I go to the kitchen and find the biggest knife I could see. Then I just sit there, and stab my stomach over and over and over again with the knife. My husband walks through the door, sees me covered in blood doing this, crying now that he has seen his wife and his baby(ies) get hurt over and over again.

Why am I having this dream? Its always this dream or a dream were I lose a baby. Can someone help me understand why this dream is repetitive?
