Worried about nothing?

So I just figured out I'm pregnant, so I called my normal doctor in hope that I can get in soon to get blood work, and I can't get in until April 23rd. I would be almost 12 weeks at that point.

I of course said that I don't feel comfortable going that long and they responded with you'll be fine.

Am I overreacting or do I have validation to be upset? I'm not as worried about an ultrasound but waiting that long for even blood work?
