The gestation period of a guppy is 22-26 days. It will take longer if the tank's condition is less then ideal and the females are stressed. When the female guppy becomes fertilized, a dark area near the anus, known as the gravid spot, will enlarge and darken. Guppies prefer water temperatures of about 77°F for reproduction. After giving birth, the female is ready for conception within a few hours. If a male does not mate with the female soon after birth, the female can use stored sperm from the previous mating.

Way too many variables to give a straight answer...
Water conditions have to be just right for fish to breed. Guppies are brackish fish--they will probably never breed unless there is some non-iodine salt in their water (1/2 tsp. per gallon). If the water conditions are right, breeding takes place and 21-40 days later, the female will give birth to live fry. It's important to have plenty of hiding spaces or a breeder box as the other fish WILL try to eat them.
You can tell if your female guppies are pregnant by looking at their belly. You will see a dark spot right above the first bottom fin.

That picture shows what I'm talking about.
Hope that helps!

First of all guppies aren't brackish, they are fresh water fish. Secondly, if they were brackish 1/2 a teaspoon wouldn't be enough to make the water brackish. And all females have the dark spot, its called a gravid spot. If they are pregnant their belly will become larger and after a couple weeks you may be able to see the babies eyes.
Guppies are usually pregnant for an average of 28 days. So if you bought a pregnant female you can have babies any day now. If the water isn't right (high levels of ammonia or nitrite) or if they are under a lot of stress, from the move, then they can abort the pregnancy and start all over again.

Sometimes you can buy guppy females that are already pregnant. I have had fry within 4 days!
Learn how to sex males and females:

Make sure you have at least 1 mature male.
Make sure the tank conditions are as close to nature as possible for the species being kept. It takes about 4 weeks after conception. After birth. fry must be segregated from parents or else they will become dinner!

see it depends on the water it is and the types of fishes which are with the guppies. Actually it takes 6 weeks for guppies to breed. since you have bought it recently it will take some time for the couple to settle down in your aquarium and then breed so good luck.

Be careful when buying females already pregnant, no matter what i do they always die a couple of days after introducing them to the tank.

It depends if you have males AND females...if theyr'e all males pack a lunch!!! It won't be long, they reproduce quickly...keep your eyes on the females...they plump-up rather big , and when they "give birth" the whole tank will try to eat the fry.

I would wait until end of the week. Shock of new environment will slow any fish functions.

They might be pregnant already and give birth within days. Mine did!
