gerbil breeding

[gabrielle]

I have a male gerbil that mounted my female a week ago, but today i watched a video of gerbils breeding and mine chased each other and mounted but they didn't stop at the end like the gerbils in the video. Today i put them back together and the male mounted the female but she attacked him, but a couple minutes later he mounted her again and she didn't attack him. Was she pregnant the first time or the second time?

Pregnant gerbils don't go into heat (and thus don't mate). So she didn't get pregnant a week ago, no.
