First trimester anxiety

I’m FTM and will be 11 weeks tomorrow.

I keep having this silly feeling that it’s all in my head, there’s nothing there and I’ll be really embarrassed to tell all of my family I overreacted and I wasn’t pregnant in the first place. Like I’m overestimating everything - it sounds silly but it’s a recurring thought that keeps popping in my head.

I’ve had 3 positive tests, I’ve had my booking appointment where I gave bloods and urine, I’ve had morning sickness, severe fatigue, and I haven’t had a period since June. And my trousers no longer fit! I haven’t had any scans yet with my first one in 10 days time. So I can rationalise that I am pregnant 😅

I know it’s all in my head 😂 but does anybody else get these thoughts particularly during the first trimester?
