Many Ladies ask this question of knowing the safe period when pregnancy can not occur when they have unprotected sex with their partner. The safe period is certainly a period when a couple or two partners can have sex without necessarily fearing of pregnancy occurring. Pregnancy Mostly occurs halfway through periods when ovulation (release of the female egg) takes place. However, it becomes difficult and a sort of a challenge to know when exactly the egg is released from the ovary and what is more confusing is that a lot of Ladies can be fertile for a couple of days around the time ovulation occurs. So having unprotected sex during the safe period days can not guarantee of pregnancy not taking place which means you are required not to take chance by using contraceptive like plan b, the pill and ipill. However if you still want to take chance and want to have sex during the safe periods, this is how you can determine when it is SAFE: To calculate and know the safe period for having sex and not getting pregnant, you need to know thoroughly about the menstrual cycle and how it takes place. The menstrual cycle varies from 26 to 31 days from woman to woman and the safe period to avoid pregnancy should be calculated as below: A. The longest cycle days subtracted by ten days gives the last day of the fertile period: 31 days- 10days= 21 day B. The shortest cycle days subtracted by 18 days gives the first day of fertile period: 26 days- 18 days= 8th day. From the calculation above the unsafe period (the fertile period) to have sex and get pregnant is 8th to 21st day of each menstrual cycle. That time period is when you can get pregnant. However the effectiveness of this method all depends on if you have made your calculations the right way. To identify the shortest and longest period cycles you are required to make an observation and draw a conclusion from it. For example you can observe your periods for 6 months and determine the number of days between starting date and the next period after which you will be in a good position to identify or know the shortest and longest period cycles which will in turn help you in knowing the safe and unsafe periods to have sex. Ladies, remember, if you do not want to have a baby, there are two main options: either do not have sex, or if you are going to have sex, use contraception. Contraceptives work by preventing the sperms from fertilizing the egg, and this can be done in several different ways. There are two main types of contraception: 1. Barrier methods - which physically prevent sperm from swimming into the uterus and fertilizing the egg 2. Hormonal methods - which alter the hormonal cycle of a woman to prevent fertilization. There are two main types of hormonal contraceptive which can be used by teens: the contraceptive pill, and the inject able hormonal contraceptive. If used properly, both are extremely effective in providing protection against pregnancy. But they provide no protection at all against sexually transmitted diseases. For very good protection against both pregnancy and sexually transmitted diseases like HIV, a hormonal method should be used at the same time as the male condom. 3. The female condom: It is not as widely available as the male condom and it is more expensive. It is however very useful when the man either will not, or cannot, use a male condom. It is like a male condom, except it is bigger and worn inside the vagina. 4. If a Lady has had unprotected sex, but does not want to have a baby, one option is the morning after pill. This is an emergency contraceptive that can prevent pregnancy, when taken after sex. The name is actually a little bit misleading, as it does not necessarily have to be taken the morning after it can work up to 72 hours after youve had sex. However, it is most effective when taken within 24 hours of sex, and the sooner you take it, the better. Other types of contraception, which are generally not used by young people, include natural methods such as only having sex at certain times of the month and intrauterine system (IUS), also known as 'the coil', are generally not used by young people although in some countries, they are now considered suitable for all age groups. How do you know which one to choose? Different methods of contraception have their individual advantages and disadvantages. There is no single best method of contraception, so you have to decide which is most suitable for you. Whatever your situation, there should be a contraception option that works for you. For many people, barrier methods of contraception are best, because they not only prevent pregnancy, but also prevent other sexually transmitted diseases being passed on during sex. Always remember, the most effective way to avoid having a baby is to not have sexual intercourse. Abstinence is the most effective method of birth control, and many young people around the world choose this option. For some, this means not having sex until they are married. For others, it can mean different things, like waiting until they have found a stable partner who they feel comfortable with. You need to decide what is best for you personally. Do not feel pressured into having sex just because others are. It is important to feel that you are ready before you start having sex.
