She's pregnant, and got pregnant!

For those concerned with reproduction, at the margins! 

It doesn't look like there is much of this happening, (no surprise, no kidding).

On an related search, I discovered "types of twins".  (I thought there were more!)
Conjoined - a single initial embryo splits but doesn't fully separate...
Superfetation - twins conceived separately
Heteropaternal Superfecundation - twins from different fathers
Polar Body Twins: "Half Identical" possibly one egg splits and each half meets a sperm. Weird! 
Monozygotic - two identical same gender copies
Mirror Image Twins - also Monozygotic (one initial egg) these twins aren't identical in fun ways.
Parasitic - this is too gross.
Semi-Identical - only one known pair!  One egg, two sperm, one is a hermaphrodite.
Twins with different birthdays - "twins have been born days, even weeks apart! "
Twins of different races - a special case of HeteroSuper above. Also possible with bi-racial parents!

Twins happen ("naturally") with more frequency in older mothers, (over 35) of which there are an abundance.

Fertility treatments are (now) a major source.  Octo-Mom lives way too close to me!

Our bodies are wonderful, let's fully enjoy them as we live long and die out!

Vehemently Yours,
