If you are concerned about a possible pregnancy or are considering an abortion, understanding these common misconceptions is the first step.

1. Can you get pregnant during your period?

The Reality: Yes. While many believe menstruation prevents pregnancy, the possibility exists for two reasons:

  • Sperm Longevity: Sperm can live inside a woman’s body for up to seven days.
  • Irregular Cycles: If ovulation occurs shortly after a period, fertilization can happen.
  • Note: STDs can also be transmitted during menstruation.

2. Can certain positions prevent pregnancy?

The Reality: No. There is no sexual position or post-intercourse movement that prevents pregnancy. Sperm can travel into the uterus and fertilize an egg regardless of gravity or physical positioning.

3. Can you get pregnant the first time you have sex?

The Reality: Yes. Pregnancy can occur every time unprotected sex takes place, including the very first time. You do not need to have sex multiple times to conceive; the chance of pregnancy is present during any instance of intercourse.

4. Is birth control 100% effective?

The Reality: No birth control method is 100% effective.

  • Failure Rates: All methods have a failure rate, meaning pregnancy can occur even when used correctly.
  • STD Protection: Prescription birth control does not protect against STDs. Per the CDC, the only ways to prevent STDs are abstinence or a mutually monogamous relationship with an uninfected partner.

5. Is the “Morning After Pill” effective for everyone?

The Reality: Effectiveness varies. The “morning after pill” is not a universal solution and can be impacted by:

  • Weight: Certain body weights can lower the pill’s efficacy.
  • Timing: Effectiveness decreases the longer you wait after intercourse.
  • Medications: Barbiturates or herbal supplements like St. John’s Wort can interfere with the medication.

6. Is birth control always safe and simple?

The Reality: While often marketed as side-effect free, birth control carries risks.

  • Common Effects: Nausea, headaches, breast tenderness, and spotting.
  • Serious Risks: High blood pressure, blood clots, heart attack, and stroke. Always consult a doctor regarding your medical history and potential risks.
