God and your faith in the word of God is the best and only way you can use to get pregnant. No one knows how babies are form, neither do anyone of us know how the sperm meet with the egg. But your faith, what you believe in, your relationship with God is what makes you pregnant.
It takes nine months for one to make babies, so everything has a step, time, relax, have faith, just believe, never give up. God created us for the purpose for us to multiple, he created us momies here as men with womb that is why we are called women. So if we cannot be pregnant he should have made us men instead of female. Look up to him for him only will do it.
