Bleeding 4 days post IUI?

Hi! I had <a href="https://glowing.com/glow-fertility-program">IUI</a> on Monday, following 5 days of Femara (following 3 unsuccessful rounds of clomid). I started very light, light red spotting this afternoon. Is this too early for implantation spotting? I've never had spotting at this stage of my cycle before. I'm having light cramping as well. Good signs, bad signs, normal?
