Fetus vital signs attributes

Note about fosterId: FosterID should be set if there is more than 1 fetus, and we recommend using sequential IDs (1,2,3 etc.). During the early stages of the pregnancy it might be hard to determine which fetus is which, but if/when there are any notable differences between them (sex, size etc.), we recommend using the note field to describe this, so that it is possible to differentiate them between appointments.
