I had this happen to mine.
she lost her mucas plug, keep an eye on her, should be any time. To be safe I would call a vet if she hasn't had anything in a couple of days. my first timer did this and i was panicky, then one day when i least expected it, she has twins, even a bigger suprise!

I wondered if it was.But it was very bloody mucus.She's really bagging up fast.But she is so small I didn't think she was pregnant.
Ann.

when it is their first time, they won't show very much with just one, mine didn't until just before birt when she dropped the baby into birthing postition.
we had bought a goat last september, she was so skinny, in october she started bagging up, and in november she had a baby. suprise, she never looked pregnant either.
