Confused! Period? Implantation? Imaginary period idk

Iishia

So my what I thought was a period started for maybe 30mins to an hr and then stopped. My pad had two red spots on it. I’m currently 12DPO and <a href="https://glowing.com/glow-fertility-program">IUI</a>. My period isn’t due for another 2

Days. My period never starts and disappear so I’ve been constantly going to the bathroom to check to see if it’s started back again and nothing just cervical mucus with a pink ting. From my understanding implantation bleeding is supposed to be light pink or brown so I was convinced it was my period but now it’s gone and my cervix is still high and pretty moist. I’m so confused 🤷🏽‍♀️
