In denial

I’m currently pregnant with my 2nd child. I was 8 weeks on 8/13. I had my first ultrasound that day and my husband and I got to see our peanut for the first time. I’ve taken probably 20 pregnancy tests before the ultrasound (I was just under 4 weeks when I started testing), have some serious nausea, food aversions/cravings and we’ve even seen the heartbeat and it’s bpm was 163.

We haven’t told any of our friends and family just yet but will be soon because I’m already showing a little bit.

Why am I in denial about being pregnant again? I’m just not understanding why I feel this way.
