Java around the world

I have two guppies, a male and a female, in a 10 gallon tank with a female beta, some neons and a clown loach. None of the fish are aggressive to each other. Even the beta is gentle and does not bother the neons or the guppies. In fact, the only slightly aggressive fish in the tank is the guppies, and out of them the female is the most aggressive. The female is pregnant and I think within a week of giving birth. This is the first time for me to experience this and I don't want to put the fry (or the mother) in danger. I wasn't sure what to do, so last night I put her into a fry net with some Java moss, Anacharis and some other floating plants. She seems really unhappy in there. She looks stressed and swims at the net edges looking for a way out. I'm not sure what to do. Do I take her out of the net and then won't the babies be at risk in the main tank when she gives birth? If she is stressed in there will she still give birth? Is she in danger? I don't have a nursery tank.
