you're 38 weeks pregnant!
Don't panic if you feel electric buzzes down your legs and inside your vagina. Baby has simply stumbled on yet another way to grab your attention -- this time, he's bumping against nerves in your pelvis.
Baby's now the size of a watermelon! The last bits of vernix caseosa (the white goo keeping baby's skin moist) and lanugo (downy hair) are slowly shedding into your amniotic fluid. Baby's head is about the same circumference as her abdomen, and her head could be covered in an inch or so of hair.
