Examiners report
There was some concern on the terminology used in the question. The term early pregnancy is not too scientific but a more definite time span might have confused candidates, which is why it was not used. This question proved to be a very good discriminator, so it probably did not distract candidates, as the more able candidates were getting this question right.
