I have no clue

I feel like I’m over sensitive. I know my husband wants kids with me. I know we love each other. But sometimes I wish I felt more solid and sure about things. I wish there were signs telling me this is the right decision. That it’s okay if we want a baby now. I just need to feel it. I’m scared of marriage and everything it brings, I believe in it with my husband. But I don’t want my marriage to fall apart over me waiting for a baby sign. All over the place. Help?
