A tattoo of sorts on the stomach used to count how many times a character got pregnant/how many children that character had/and how many are currently being carried.
Usually more tattoos are added the more children one has, similar to a tally.
The symbol is often a heart or child icon, but sometimes the number of persons or details are written directly in text.
The usual format is filled hearts/child icon = births, hollow hearts/child icon = currently carrying and how many inside the current pregnancy, and if telling genders of babies apart they are also colored, typically red/pink for girls and blue for boys.
When a child has died due to miscarriage, abortion, etc., a heart break symbol or a child icon with a diagonal line is often used.
When the purpose is to abort a child from the beginning, it is called an “abortion mark” and is distinguished from a “pregnancy mark”.
