NO it isnt good, alot of places wolf crosses are illegal to own, that means that if they are taken to a vet they may be put down, if they ever end up in a shelter or SPCA they will be put down. If I were you I would tae her to the vet and have her spayed.
When a bitch is in heat, her vulva swells up..If she is not pregnant, within 2 weeks after the heat is over, she should shrink back down and firm up. If she was bred and is pregnant, most of the time, there will still be swelling, but not as much as in heat. if it looks like an acorn when not in heat, and a puffy marshmellow in heat, about halfway is what it should be like. and it won't go back down.. Most bitches do not show until they are about 2-3 weeks from due date.
Sounds like you need to get her to the vet and get her spayed asap. I don't like the thought of aborting the babies but it is a huge responsibility to care for puppies, especially if they are going to be big dogs and have the possibility of having wolf in them. They will constantly want to run and sometimes don't make very good pets. Good luck in your decision, our prayers are with you.
