Anxiety about miscarriage

Kayla • 22! married to the love of my life! Love photography and nature.
So, I was doing alright with my anxiety until I started looking at magazines and stuff wanting to purchase baby items, stuff I will need that I could buy now. My husband on the other hand wants to wait because he says there's still a risk of miscarriage, I wasn't even thinking about it until now. Now it has my anxiety through the roof, I would love to go shopping with some friends and family but can't and people are sending us gifts already. I don't know what to do or calm myself, I already assume I am okay because I had a double dose of antibiotics and managed to get CDIFF and lose 16 pounds and baby is still okay at 12w3. Does anyone else have anxiety after the "clear" mark?
