Eli5 How do birth control pills not cause a build up in uterus lining

190 views

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?

The ‘bleeding’ that happens when you’re on the pill is not a true period. The catholic church got involved in the 1950’s when birth control was becoming a thing. You have this ‘withdrawl bleeding’ so that you have the ‘appearance of having a period’. You can absolutely go 100% on the pill all the time as there is no benefit to this ‘withdrawl bleeding’ other than to appear like you are not on birth control and are being a good catholic.

On the pill, your womb lining doesn’t really grow, so there’s no buildup to be concerned about.
