My Prissie miscarried yesterday afternoon.

We are not sure if she miscarried all babies or just one or two. We are going for a ultrasound next Thursday to see if she still has some babies. We don't know what caused her to miscarry, she has had a normal pregnancy till now, her due date is Nov. 2nd. She is 5 years old and in perfect health. This would've been her fourth and last litter, we were planning on having her spayed after this litter, that hasn't changed. She is at work with me today so that I can keep an eye on her, I normally take off when she is near delivery so that I can be at home with her. I can't imagine what she was going through yesterday when this happened, I'm so upset about that.
She had a rough night last night, she just couldn't get comfortable, I think she was looking for her babies. She seems to be doing fine today, but please keep her in your thoughts and prayers. I pray that everything is alright with her, that is my main concern, she is our precious girl and we just want to make sure she is okay.
Here are a couple of pictures of her at work with me today.
