How can I get my wife praganant?

The usual way, but.. If a couple has been trying to get pregnant the usual way, having sex without any birth control products, at least 3 times a week, for many months, then it is time for the man to see a urologist or fertility doctor to check his sperm, and it is time for the woman to see an ob-gyn doctor to check for ovulation, plus examine her vagina and internal female organs. Good luck!
