yeah, she'll loose alittle hair around the nipple too, also you'll notice right befor she goes into labor, her nipples will begin to produce milk and get alittle plumper and her plevic bone will begin to widen alittle. when her pelvic bone,; which you can feel near her vagina; (about an inch above the opening) is open wider than the width of your thumb, you can expect her to go into labor about anywhere from 12 to 24 hrs from when you first notice the opening. she'll most likley go into labor in the late afternoon or at night when its quiet. at the sign of labor, you'll want to give her as much privacey as you can but still be ther if she needs your assistance. its been such a long time since i had a piggie who was pregnant ( i was 9 going on 10 when my uncle got me my first piggie for my b-day, she had 4 piggies about a month after i got her). how old is she? if you do know, since piggies that have never given birth before they are 7 months will have a difficult birth. its not to scare you, but what happens is if the piggie hasn't given birth no earlier than 5 months and no later than 8 months, the pelvic bone starts to fuse together making delivery impossible and you'll have to take her to a vet to have a cesarian done, which puts the mom and babies in danger.
