This question of mine just got deleted for "not notable, disturbing and as political propaganda. No thanks", before I could answer the comment by Oddthinking:
A common form of anti-abortion rhetoric is to make people see disturbing medical images without warning/consent. Whatever your actual motivation, this question read the same way, which may be part of the reaction against it. Perhaps you could explain your motivation better so people can understand what a good answer would need to provide
I saw a few days ago a drawing of a 12 week fetus in Twitter posted by an anti-abortion user, and I was looking for a real picture of a 12 weeks fetus. I could not find a reputable source with an actual picture, and this one (which had a picture and not a drawing) had no source attached. A Google image search showed only anti-abortion blogs using it. That's it.
Probably opening this post here in meta is not the proper way to address this, but I wanted to at least be able to answer Oddthinking why I posted that question.
PD: I'm very pro abortion.
