In a normal period, the uterus lining is thickened and then shed during the period.
What happens to the lining when using birth control pills? If it’s not shed does it not just keep on getting thicker and thicker?

I would presume the uteran lining builds with the increased estrogen output of the growing egg, when on birthcontrol the estrogen level is stable so maybe the lining doesn’t grow (as large as it would normally)?
But then when you take the week of the placebo you still cycle so idk?
Also what happens with women who skip the placebo round (had a couple of girlfriends who were instructed to toss the placebo s and keeps taking the hormone pills)?
