Mini pill

Anyone here on the mini pill? How soon did you start missing a period after starting them? I've been on the mini pill about a month in a half. I've missed a pill about twice & have taken it late a few times🤦‍♀️ I've never been late on my period in my life. Except for when I found out I was pregnant both times. Even when I had the IUD birth control, I was getting periods regularly. I'm 2 days late on my period & I'm honestly having no signs of it coming... Trying to figure out if this id normal or not. Especially because I haven't been on it that long.
