In one sentence, describe what the following article is about: If you take regular birth control pills, and have simply missed a dose, you may be able to increase your dose as a form of emergency contraception. However, you should talk to your doctor or a pharmacist about the number of pills you should take.  You can also call 1-800-PLAN to discuss your options with a Planned Parenthood representative. Depending on the kind of oral contraceptive, one dose may be 4 or 5 pills. After establishing how many pills you need, take two doses within 12 hours of one another. This is considered a safe and effective pregnancy prevention method.  Take your first dose up to 5 days or up to 120 hours after unprotected sex. Take the second dose 12 hours after the first dose. An hour more or less won't make a difference. You may be tempted to take more than 4-5 pills to make sure it works, but this will not actually reduce your risk. The only thing it will do is raise your chances of an upset stomach. If you experience severe stomach pain, seek medical attention.
Summary: Determine your dosage. Take two doses. Don’t take extra pills.

In one sentence, describe what the following article is about: The change-up is a slower pitch that throws batters off-guard when expecting another fast-ball. Hold the ball completely in your palm, letting your each finger rest on the laces, and skip the finger snap when following through, instead leaving your hand open. This is often the first special pitch you should learn after the fastball. The aim of the pitch is to make the ball sink on the batter. Grip the ball with your fingers aligned with the laces, instead of across them like you would on a fastball. Keeping your elbow a little more rigid than normal, flick your wrist and follow through like as if you were throwing a basic pitch. You need the same grip as a drop pitch -- fingers aligned with the laces, not across. Curveballs move down and sideways, making them tricky for a batter to track and hit. Your throwing motion is nearly the exact same as a fastball, but you twist your wrist (counter-clockwise for righties, clockwise for lefties) as you release the ball. This causes the ball to spin sideways as it travels. The hardest pitch to throw, this ball will come up towards the batter, making it incredibly hard to hit. The goal is a pitch that has top-spin so that the bottom of the ball rotates towards the top. To throw it:  Put your middle and ring finger in between the laces, at the point where they start to come towards each other. Dig the tip of your index finger into the side of the ball. Begin your normal fastball motion, but keep your palm facing down as you come around behind your back. As you release, quickly turn your hand so that your palm faces up, as if you were turning a doorknob. Release the ball early so that it has time to rise. Remember that this is the hardest pitch to throw, and may take upwards of a year to perfect.
Summary: Throw a change-up by following through without snapping your fingers. Throw a drop pitch by gripping the ball along the laces. Throw a curveball by rotating your wrist as you release. Throw a "rise ball" with a special grip and release.

In one sentence, describe what the following article is about: Pour enough of the liquid resin mix into the mold or bezel to completely cover the bottom. Work slowly to reduce the number of air bubbles. Hold a hair dryer or heat gun roughly 4 inches (10 cm) above the resin for a minute or so. Any air bubbles trapped inside should rise to the surface and pop. Even though you'll be adding another layer of resin later, it's best to remove the air bubbles in this layer now instead of waiting until the end. Wait 15 minutes or so, allowing the resin in your mold to harden slightly. Carefully place heavy three-dimensional objects on top of the bottom layer using tweezers.  The bottom of the mold or bezel will be the front of your piece, so place the items in upside-down. By placing the heavy embellishments in between layers of resin, you help hold them in place. If you added them without using layers, the pieces would likely move around before the resin sets. Pour additional resin over the heavy embellishments, covering them completely.  This layer of resin should reach the top of the bezel or mold. You may need to adjust the position of your embellishments with a toothpick if they shift during this time. If you want a glittery background, sprinkle the glitter over the top of the mold or bezel after filling it with your final layer of resin. Glitter is small and light, so it should float on the surface of the resin as it dries. Since the top will later become the back of the piece, the glitter will create a background. If you plan to add any transparencies, dip them in a little leftover resin before placing them in the mold.  Use tweezers to dunk the transparency into the leftover resin in your measuring cup. Quickly dry the resin with your heat gun or hair dryer. Coating the transparencies will help reduce the risk of air bubbles forming between them and the resin in your mold. The bottom of your mold or bezel will end up being the front of your piece, so place the transparency in upside-down. As before, use your hair dryer or heat gun to gently bring any air bubbles to the surface, where they can pop. If you plan to use a paper background, use tweezers to carefully place the paper over the top of the resin, aligning it as evenly as possible with the opening of the mold or bezel. Make sure that the paper is upside-down when you place it in so that the decorative side shows from the front of the piece. Set the filled mold or bezel aside and cover it with a clean box. Allow the resin to cure overnight.  It is important to cover the resin as it cures to protect it from dust or other debris. Curing times can vary, so you'll need to follow the manufacturer's instructions. Only cure it long enough for the resin to be touchable. Do not wait until the resin is fully cured. Once cured, you should be able to pop the resin pieces out of their molds using your fingers.  If the pieces are still too soft to remove, try placing the mold in your freezer for 10 minutes. That should make it easier to pop the finished pieces out. At this point, the resin piece is ready to work with, but you'll need to take additional steps before you can wear it as jewelry. If you used a bezel instead of a mold, you will need to peel off the tape from the back of the bezel once the resin cures.  Do not remove the resin from the bezel. At this point, the resin charm is complete and ready to use as wearable jewelry.
Summary:
Pour a layer of resin in. Remove any air bubbles. Let the resin harden slightly before adding heavier embellishments. Cover with a final layer of resin. Add glitter, if desired. Coat transparencies in resin before adding them. Remove any air bubbles. Add any paper backgrounds. Let the resin cure. Remove the resin charms from their molds. Remove the backing from bezels.
