What if the size of the uterus is not what you expected?

If you are measuring correctly and you do not find the top of the uterus where you expect it to be, based on the date the woman gave you for her LNMP, it could mean three different things:

• The due date you got by counting from the LNMP could be wrong.
• The uterus (and the baby) could be growing too fast.
• The uterus (and the baby) could be growing too slowly.
