There are couples today who try for years to have a baby, but have not been very successful or they end up consuming too much time. This can cause them to have just one child instead of 2 or 3 which is what they really wanted. This is because a woman can only conceive up to a certain age and anytime beyond that could be a threat to their lives. This is another reason why couples cannot consume too much time trying to get pregnant and they should be aware, especially the woman, on what are the things that need to be done in order to have a baby exactly at the time that they have planned.
