Hcg at 4 weeks

Laura
Hey ladies. Had <a href="https://glowing.com/glow-fertility-program">iui</a> on Jan 30 at day 22. We were successful after three miscarriages in 2015. My question is my hcg at 2 weeks post <a href="https://glowing.com/glow-fertility-program">iui</a> was 68. Is this good? I go back tomorrow. I have been Poas and the line has stayed the same since fri. Should I be worried?
