Noise?

Question
My two rabbits have been happy rabbits for 4 monthes until two days ago. One of my rabbits that we think is a female has been making alot of noise. Its more like a grunt or squeak. She does this whenever my male rabbit goes near her or I go near her. And she'll run away. We have been thinking that shes pregnant but we thought that 2 monthes ago! she has grown large and been moving around her blankets and the male has been doing her alot! I was just wondering why does she make those noises? Nothings changed.  

Answer
They are definatly breeding and a male and female rabbit should be separated after 4 months of age. www.islandgems.net has tons of information about breeding rabbits. You will find links on palpations and stuff that you will need to know if she is pregnant. The noises she is making is that of a female who is bred or wanting bred.
