Some women are not married but they are able to conceive a child immediately. There are also some women who have been married for a long time but they have never gotten pregnant. Some women are considered to be lucky because they can get pregnant easily.
Some have tried their best to become pregnant. They have done different things just to increase their chances of getting pregnant but they have still failed. Doctors can only do so much to aid women in getting pregnant. They can suggest various methods but there is no guarantee that those methods will work.
