hai madhav,
For scorpio lagna Venus is the lord of 7 and 12 bhavas in 5th bhava Pisces. Venus is exalted. So 5th bhava results are to be taken through 7th and 12th bhavas. 5th bhava is for children, 7th bhava is for spouse and 12th bhava is for expenses. The wife will deliver a female child with a lot of expenses to the husband.
