Great Job!

Great amount of research put into this!! A suggestion that I would have is to maybe elaborate more under the heading "20th century" by including the other types of contraceptives too other than just the IUD like the nuva ring and implant etc and statistics of how many people are on it if you can find that? That way the 20th Century stands out as a bit more of a change from the 19th century with more technological advancements with birth control.
