Guppy pregnant

My both guppies look pregnant. One of them have a very dark grvid spot and otgher has yellow/clear.... But size is same. Was not sure how long left till they will give birth? I have attached the pictures too. I have put them in same tank but separate than Community tank.

Thanks in advance

It can be kind of hard to tell exactly when they are going to give birth. Maybe in another week or so?
