I think it's more or less impossible that she is pregnant again so soon after giving birth, is she still lactating? Most bitches will follow a 5-6 month cycle although some will come back on heat after 4 months.
What symptoms does she have that would suggest she's pregnant again?
Is she eating and drinking normally? If she looks bloated I think you're best getting her checked by your vet, does she have any discharge? I'd be worried about possible retained placenta or a uterine infection related to hormonal changes.
Word fail me...
No, she cannot be pregnant again, she will not ovulate until her next season. However, more importantly it is essential you do not take her out when she has puppies as you risk bringing back illness and infecting the pups, or do you have an entire male dog on the premises?
If the pups are four weeks old, ideally she should still be feeding them, most bitches naturally wean at around 6-8 weeks if allowed unlimited access to their puppies. If she is a small or toy breed (and I am assuming she may be as she had only two pups) it's actually pretty important she feeds her pup for as long as possible.
It would really be best to get her neutered, there are so many unwanted dogs and whelping in very dangerous for a bitch.

Are you letting her out by herself that would mean she could have been impregnanted? If so, are you purposely trying to breed her? If you aren't, then I would keep her inside unless you are outside with her, then in a few months, when pup is fully independent and not nursing anymore, I would go and get her neutered, then you never have to worry about this again!
I just see these types of threads time and time again and wonder, if you don't want to breed your pet, then get them neutered, as soon as you get them, have them neutered. It's that simple.
Unfortunately though, you can't try and make other people responsible owners, all you can do, if you don't want to breed your pet, is desex them. (OP said she didn't want to breed her dog.)
If you want to breed your dog, you can be responsible and have all the fencing in the world put up, but unfortunately male dogs tend to have super ability to gain access to a female in heat. I suppose that is a risk you have to take when you don't desex and let your dog outside unsupervised, even if it is in a fenced yard.
I still think the simple answer, if you don't want to breed, is to have your pet desexed.
