Emergency contraception is used after a sexual intercourse in order to avoid unwanted pregnancies. There are different types of contraception which provide the results in different ways. They are discussed below in detail.
Barrier method refers to the use of physical barriers like condoms and cervical caps that directly prevent the sperms from entering the vagina. This method may be comparatively safer for the health as it does not disrupt the naturally occurring hormonal levels of the body. However, it does not guarantee 100 % against child birth control. In fact, if women are using vaginal caps, it is best to have them fitted by a doctor and refitted again from time to time to ensure that it stays secure.
There is also another method that does not involve hormonal changes hormonal changes throughout the body. This involves inserting copper rings that release estrogen and progestin into the vagina. This, however, may not exactly be an emergency contraception as it needs to have been inserted before having sex.
Pills are the most common form of emergency contraception. They can be bought from any medical store without having to produce any sort of prescription or age verification. There are however a few pills that strictly require doctor’s prescription. These pills have to be taken within a stipulated time period as recommended by the manufacturer. Most pills, for example, have to be taken within 72 hours of intercourse. The pills are effective when taken within this time period. However, if it is delayed, there is no guarantee that it will show 100% effectiveness.
There are two types of birth control pills, the ones that are to be taken on a daily basis and the ones that are to be taken only when an intercourse takes place. Both work by altering the hormonal balance of the body.
The pills that are taken on a daily basis will keep the eggs from leaving the ovary and they also tend to thicken the vaginal mucus so that the sperms are unable to sin their way into the uterus. It is best to consult the doctor before settling for any such medication so that there are no serious side effects in the aftermath. However, women taking the daily pills have reported of having had weight gains even though other side effects were not visible.
Estrogen and progestin shots are also very effective in preventing pregnancies. They work in the same way as the emergency pills. The shots can be taken both before and after the intercourse. Depending on the dosage, one shot can last for a couple of months. Shots are also best for those people who may not find it convenient to take a pill each day. For women who are breastfeeding a child, it is best to go for progestin-only shots as this will not affect the quality and quantity of the milk secreted. There are some shots that not only prevent pregnancy but also protect the body from endometrial cancer and iron deficiencies. However, there are a few downsides surrounding the use of shots, which include weight gain and irregular periods.
