This is interesting special case where a man has 13 wives and all pregnant women at the same time and in the same month. Although it is strange to us, a man who has 13 wives and all pregnant women at the same time, however in your country this is normal. All women live together and care for each other. They live like a big family, give each other advice on pregnancy, children and her husband.
Тhey live as a happy family and wife are all extremely happy about her pregnancy and everyone they feel very well.
Although this is perfectly legal in your country, but this is the first man to have all pregnant women at once and the distance between each pregnancy is 3 weeks to 5 weeks.
