Is this bunny girl pregnant?

To be honest the answer to this question is 'I don't know', but I have palpatated her as advised by many things I have read and I can feel some little lumps I have not felt before. However it may be that she is just getting more used to having it done and relaxing more and I am feeling internal organs or little rabbit pellet poos working their way through her.
When we mated her a few weeks ago we left her and bunny boy together for about 2 days despite advice that you should only leave them together a short while - that technique clearly wasn't working and we have never seen them be aggressive towards one another.
We will just have to wait and see...
