About copyright
Hello. It appeared as if you had copied some text almost word by word and put it into the article Placenta praevia. We can't republish copyrighted text here on Wikipedia, so I've reverted your edits.

You can of course add material in your own words, if it isn't a close paraphrasing of the original text. But, it is necessary to cite sources. You can take a look at this tutorial which explains how to add references to an article. It's very easy, and often automatic, to add citations when using journals or webpages.

Thank you :) – Þjarkur (talk) 19:37, 2 March 2019 (UTC)
