Birth control shot is an effective birth controlling method in which an injection of progestin (a hormone) is given on the upper arm or in the buttocks of a woman once every 3 months to protect her from conceiving. This birth controlling injection stops woman’s body from releasing an egg each month. It is a very effective method, but a woman can get pregnant if she does not receive the next shot within 3 months.
How does birth control shot affect menstrual cycles?
In most women, menstrual cycles become fewer and lighter. After 6-12 months, half of the women using birth control injection report a complete stoppage of periods. Some women may also experience longer periods with heavy bleeding.
How does birth control shot work?
The progestin inserted by the birth control injection prevents the ovaries from releasing eggs. Progestin does not let the sperms move to your eggs as it thickens your cervical mucus thus, preventing fertilisation. Progestin also thins the uterus lining, affecting its shape so a fertilised egg fails to attach to the uterus.
Advantages of birth control shot
Side effects of birth control shot
Birth control shot or birth control injection is taken every 12 weeks to prevent pregnancy. This shot contains a hormone called progestin, which is similar to a woman’s natural hormones. This injection does not contain estrogens (which affects milk production) and therefore, is suitable for breastfeeding women. Birth control shot majorly affects the menstruation cycle of a woman, but is a highly effective method of birth control. Before taking a birth control shot, you must consult a doctor.
