Day 28 HCG levels?

Kristin • Two boys and two miscarriages, pregnant and due in May! 🌈
I am on day 28 of my cycle following our first <a href="https://glowing.com/glow-fertility-program">IUI</a>. I had my <a href="https://glowing.com/glow-fertility-program">IUI</a> exactly 2 weeks ago and had my first positive pregnancy test 3 days ago. They did my beta today and it was 28.5. Does that seem too low?
