The uterine lining builds-up following ovulation in preparation for possible pregnancy, to allow the zygote to implant and nourish the growing 'baby'. If pregnancy doesn't occur the drop in progesterone triggers the uterus lining to break down, this is called menstruation.

Does the lining of your uterus always come out during your period?

Yes, it does, unless it did not build up in the first place. As soon as your period ends, the womb lining begins to build up and thicken so that if the egg is fertilised, there will be a thick, safe, spongy environment for it to implant in. If the egg has not been fertilised, it will break down during your period because it is not needed. However, sometimes, the right hormones are not being produced or not enough of them are produced and the womb lining does not build up, therefore it does not break down either

Why does the uterus lining get thinner during the period?

The uterus lining, or endometrium, thickens in preparation for a potential pregnancy each month. If fertilization does not occur, hormonal changes lead to a decrease in estrogen and progesterone levels, which causes the endometrium to break down and shed. This shedding results in menstruation, during which the lining becomes thinner as it is expelled from the body. In the absence of pregnancy, the thinning of the lining is a natural part of the menstrual cycle.
