Twinging/pulling in belly button that traveled to cervix. Was that maybe implantation?

RyRy

DH and I did <a href="https://glowing.com/glow-fertility-program">IUI</a> Monday morning around 10am. Around noon today I was having this pulling, sharp feeling in my belly button that felt like it traveled to my cervix, if that makes sense? It didn’t last long at all, just long enough for me to notice and think “that’s weird and new”.

Just wondering if that maybe sounds like implantation cramping, or if others have had it? Technically today puts me at 8dpo, but only 5 days after <a href="https://glowing.com/glow-fertility-program">IUI</a>.
