Contraceptive methods
Methods of contraception include oral contraceptive pills, implants, injectables, patches, vaginal rings, Intra uterine devices, condoms, male and female sterilization, lactational amenorrhea methods, withdrawal and fertility awareness based methods. These methods have different mechanisms of action and effectiveness in preventing unintended pregnancy. Effectiveness of methods is measured by the number of pregnancies per 100 women using the method per year. Methods are classified by their effectiveness as commonly used into: Very effective (0–0.9 pregnancies per 100 women); Effective (1-9 pregnancies per 100 women); Moderately effective (10-19 pregnancies per 100 women); Less effective (20 or more pregnancies per 100 women
Ultrasound
An ultrasound helps you find out whether the fetus is developing normally. Your doctor might recommend that you have 1 or more ultrasounds to confirm the gestation of the pregnancy or at different points in your pregnancy to check the anatomy of the fetus for defects or problems.
Depending on how far along your pregnancy is, ultrasound images help your doctor:
• Estimate your due date
• See the position of the placenta
• See the size, position, movement, breathing, and heart rate of the fetus
• See the amount of amniotic fluid in your uterus
• Find multiple pregnancies (twins, triplets, etc).
