What Do I Do When I Go in for My Shot?
When availing of an injectable contraceptive, you will be given one shot. You’ll have to come back for another every 12-13 weeks or 3 months, making a total of 4 shots a year. You don’t have to do anything prior to receiving your first shot, and if you have your first shot at 7 days after the start of your period, the effects of the shot will immediately protect you from pregnancy. However, if your shot was administered at any other time during your cycle, you’ll have to use other forms of contraceptives for at least a week before the drug takes effect.
After taking your first shot, be sure to take note of when your next check up and shot administration will be (3 months from your first shot) by marking it on a calendar or having your partner remind you.
What Happens if I Miss One of My Shots?
If you miss your follow up shot and have had sex within 2 weeks after your scheduled shot, you may have to take a pregnancy test as the effect of the progesterone shot may have already worn off, exposing you to becoming pregnant.
What are the Birth Control Injection Side Effects?
The most commonly seen birth control injection side effects of Medroxyprogesterone acetate (MPA) are weight gain and menstrual irregularities.
Studies have shown that people typically gain an average of around 3 kilograms while taking MPA. Half of the people who take MPA have noted having irregularity in their menses during their first year of taking the drug.
After around 2 years, the menstrual irregularities occur less frequently and decrease the longer you take the contraceptives. In fact, some studies show that half the people actually experience amenorrhea (absence of menstruation) during their first year of taking the drug.
