Implantation bleeding??

Alyssa • Mommy 💖 trying for #3💗 Baby #2 is in heaven💙 Married to my best friend 💞

Soo my iud was removed August 14th. I had a normal period and it ended the 18th, we started ttc just after and I started having light bleeding yesterday, but today I woke up still bleeding. My thoughts were it could be implantation bleeding but I don't know how long that's supposed to last. What could this mean??😭😭
