Delusional about being pregnant

Cee • TTC with baby # 1.
I think the fact of me wanting to be pregnant makes me think I'm having pregnancy synthoms . I literally have to pee like every 15 -20 minutes. I crave certain foods. My breasts are appearing bigger. I don't know if it's all in my head or I just really want to be pregnant . I took a test Tuesday & Wednesday ,and both of them were a BFN . Today I go into a clinic and take another . I'm praying for a BFP . Me and my boyfriend want a baby so I'm hoping for the best yet prepared for the worst. Today will be the confirmation I need to just " let it go " , and just keep trying . Anyone else swear they're getting signs of pregnancy yet know they're not ? :(
