17dpiui and no AF

Steff

I am 17dpiui and no sign of AF. I know when I ovulated because we confirmed it with an ultrasound. In fact when we went in for <a href="https://glowing.com/glow-fertility-program">IUI</a>, I had already ovulated so I may even be 18dpiui. But anyways has this happened to anyone? I keep getting BFN. I feel like it’s too late to get a BFP.
