Period randomly stopping?

I’m on cerelle (mini pill) and I’ve been on this one for 5 and a half months. This pill makes me have two periods a month (thinking of changing my pill again but idk this is my third one and the best of the ones I’ve had). However my last period, two weeks ago was so light I didn’t even need a pad or a panty liner, and my period is currently starting but all it is is just a tiny bit of spotting and cramping. Don’t think I’m pregnant, could my pill randomly stop making me have my period even though I’ve been taking it for a while? I know some of the side effects of this pill is irregular periods (which I have definitely been having) and sometimes no period at all
