Rattie tat tat

A friend has told me today that she is giving me some guppies, well 2 and they look like the above (although that isn't a pic of them).
I am slightly worried about them dropping fry but figured that if they did and I had not noticed or am not around, my bettas will get them, so there wouldn't be a high survival rate.
Is a guppies gestation period around 30 days? If I could get a rough estimate, I could be prepared.
My substrate is sand, there are alot of plant hiding places and pebbles.
