We bought Star 1 year and 3 days ago. Below is a link to her photos from June 2011 - today.

She's obviously gained a lot of weight over the last year. I didn't realize how much until I compared her pics. She also has edema in the milk vein area that is considerably larger today than yesterday. Yesterday and the past week it was swollen, but not like it is today. TMK, she's a maiden mare.
Before anyone gets upset, the vet is coming out next week to see what's up with her. It's possible she has a health issue going on; it's also possible (although I doubt) that she's pregnant.
Three possible pregnancy scenarios: She was exposed right before I bought her and is going over, although I don't think she's large enough to be full term. I know every horse is different. A new horse was brought next door about 6-7 months ago. I haven't checked with the owner (they have since moved) to see if the horse had been recently gelded where he was still fertile when he was brought over (I know he wouldn't have brought a stud over); or we have a rogue horse that got in and out of the pasture unnoticed.
So I thought it would be interesting to get your opinions while we wait on the vet's opinion next week. If palpating doesn't confirm a pregnancy, he will do bloodwork and we'll investigate until we determine what's going on.
Add'l info: Her feed has been reduced over the past few months (I know, we never thought there was a chance she was preggo) and she's still gaining quite a bit as you can see by the pics. She has access to pasture all day, but is fed twice a day with hay at each feeding. Her demeanor is the same as it's always been. She's very quiet. But today she spooked in place while grazing for no apparent reason. She didn't lift her head as if she saw something. Never fully raised it from grazing just jumped and jerked and went right back to eating.
