Is Anyone In denial about their pregnancy?

I am 5 weeks pregnant and I am in denial about my pregnancy. I keep doubting myself that this isn’t real! Or that I’m not pregnant and that something bad is going to happen. I am super protective over my belly. My pregnancy So far is positive. My last pregnancy with my ex was terrible and I was abused while pregnant and a single mother and sad this pregnancy with my new partner is happy and he’s kissing my belly and working overtime to ensure we are financially ok. And being amazing and It’s hard for me to adjust to happy and positive things.

Would this feeling go away?
