Pill causing period everyday!!

Yasmin • I’m from wayyyy up north

I started the progesterone only pill in early january and everything was fine until around early march when i started a random period - this very light but not light enough for a big liner. It has lasted till today and is ongoing. Sometimes the bleed is really light but it will go back to being heavier the next day. I’ve not experienced any cramping or anything else unusual and have never missed a pill... what is going on? I understand that spotting after taking a new pill is usual but this is kinda inconvenient...

anyone else with the same experience?
