Pregnant rabbit but not sure??

Hi
I bred my rabbit, Cocoa on 1/25 and this is her last week of being pregnant if she is.

This is my first time with a potentially pregnant rabbit so I didn't wanna palpate her. The buck fell off 2 times when we bred and there wasn't any sperm on her. Her nipples look more distinct and her tummy feels a little tender.
She has mood swings and she grunts at me and hops away when I go to touch her stomach.

Do I have a pregnant rabbit or not please?
