Despite the popular thinking, there are still a lot of women out there who do not understand the fundamentals related to getting pregnant and hence you will not be surprised that the result of this is a very high number of pregnancies that are not planned. In such cases, often the privacy of the said female is the main factor which needs protection. But since in our society, you are required to go to a hospital or a medical practitioner/doctor, this privacy pretty much ceases to exist.
There is a public or private record of everything which is somewhere filed of you even if you do these things secretly. In such a case, a wiser thing to do would be to use the age old wisdom rather than rely too much on external help. Before you write off the homemade pregnancy test, I would suggest that you recommend one. There is no risk involved, physical or non-physical and these are very safe while being cost effective. The best thing remains that they completely shield your privacy limits and give you an upper hand and some amount of time to make a decision while you are faced with this unexpected change in your life.
