PLZ HELP!!!! is my rabbit pregnant?

is my rabbit pregnant? i have a rabbit (female) and it was given to me a couple weeks ago. my friend gave me because she had so much. i dont have a male. yesterday i saw the rabbit with medium tummy and now little larger than usual my mum says that maybe she eats so much. my rabbit doesnt pul her hair to make a nest but i think when she is ready she will (if she is pregnant) i wish she is because i never had a animal that gave birth. so plz answer. i cant go to the vet
