Talk me out of something crazy

So we have a festival we go to every year and its Oct 11-14th. My first edd was the 9th and after my dating scan it's now the 12th but I still want to try to go to the festival. Why do I still want to try to go?! I had the hotel booked about 4 months ago way before I thought I'd be pregnant. I was so prepared for it 😭😫
