These are the mistakes you can make when you use contraception.

You might be thinking that you're taking appropriate precautions to avoid an unwanted pregnancy or to prevent sexually transmitted diseases, but the question is, are these defence strategies effective and are you using them in the right way? Probably not.

I am always surprised by the number of people I see in my medical practices, which by accident are pregnant even though they had claimed to have taken protective measures”, said Paul Turek, a sex health expert.

If you or your partner are using an anti - pregnancy pill, you no longer care about an unplanned pregnancy, do you? Just because someone can be under the effect of this tablet doesn't mean you have to feel 100% secure.

You must remember that in the real world, anti- expectant medicines fail in 10-20% of cases”, Dr. Turek. “If you don't take the tablets at the same time, or by accident you don't get one day, then you should be aware of the risks you're taking from”, he added.

You must always calculate the period of ovulation. Doctors always recommend that each woman calculate the days of the cycle, and determine whether it is time to get pregnant or not.

Sexual transmitted infections, especially herpes and Chlamydia, are some of the most common infections in America and other parts of the world. One of the ways to prevent their spread and transmission is to conduct the STDs test. According to Dr. People should always ask their partners if they've done this test or not.

One of the most frequent mistakes is the mistaking of the condom and engaging in relationships when you are under the influence of alcohol or drugs.
