Article: The antenna, yet unused until this point, is now ready to attach. Insert one end of the antenna into the hole directly above the empty lead of the 33pF capacitor. This is the same lead you just placed out of the way four columns away to the left. You can improve reception by spooling the wire of your antenna across the room as far as possible, or by winding it into a coil as described in the step on making the antenna. Insert one lead of the variable capacitor into the hole above the rightmost lead of the 33pF capacitor. The other lead connects with the black jumper wire in the long, connected row at the bottom. Use the 5 inches (12.7cm) of slack on either side of the coil to fasten it with the variable capacitor and black jumper wire in the long, connected bottom row. The remaining lead attaches at in the hole below the junction of the variable capacitor, the 10nF capacitor and the 33pF capacitor. Place your speaker on the table to the right of the variable capacitor. The red lead goes into the topmost row of the board to connect with the red jumper wire. The black lead goes into the hole directly above the unused lead of your 22uF electrolytic capacitor, on the right side of the capacitor. In many situations, you'll need to untwist the wires for the black and red leads attached to your speaker so they can be tied in to the radio circuit. Now that your circuit is finished, all it needs is some juice. Use electrical tape to attach wires to the positive and negative sides of the 9-volt battery. Then: Add the positive wire (usually red) to any hole on the topmost row of the breadboard so it connects the speaker and the red jumper wire. Add the negative wire (usually black) to any hole on the bottommost row of the breadboard to supply the black jumper and variable capacitor with current. Once the circuit has power, the electricity will begin to flow to the amp and the speaker. The speaker should now be making sound, though it might only be faint noise or static. This is a good indication that all of your components are correctly connected. Turn the variable tuner slowly to shift the frequency your radio is reading and find audible radio stations. The further away from AM radio stations you live, the weaker the signals will be. Be patient and turn the knob slowly. With a little patience, it's likely you'll be able to pick up an AM radio station. Circuits can be touchy, and many require troubleshooting, especially if this is the first circuit you've ever built. All leads need to be firmly inserted into holes, and each part of the circuit needs to be hooked up in the right fashion for it to operate. Sometimes you may have thought that you've pushed the lead all the way in to the board without it actually making a good connection. Inspect your connections on the breadboard to see if you have not connected a component in an adjacent column. The adjacent columns are not connected, therefore that component will not be connected to the others and may even be connected to the wrong item. The rows at the top and bottom on the breadboard are separate, make sure that the holes where the jumper wires are plugged in belong to the same row, not adjacent rows. Some breadboards have the top and bottom rows split into a left side and a right side. This is used when there are 2 different voltages in a circuit. In this radio, there is only one voltage is used. If the jumper wires are connected such that one is in the left side of a row and one is in the right side of a row, the radio will not work. The solution is to connect the jumpers in the same group of 5 holes of the same row, or to bridge the two rows with a small jumper wire at the middle of the rows. Adjust connections until you can hear audio when power is supplied. If this fails to work, you may need to rebuild the circuit from scratch.
Question: What is a summary of what this article is about?
Attach the antenna. Connect your variable capacitor. Attach the inductor coil. Plug in the speaker. Attach your power source. Listen to the speaker for noise. Turn the variable tuner to adjust the frequency. Troubleshoot the circuit.
Article: When you forget a pill, take the pill as soon as you remember and take the next pill at the regular time. Certain combination pills, especially multiphasic pills, may have additional instructions that you should follow. For most pills, if you don't remember until the next day, you should take two pills on that day. If you forget your pill for two days, take two pills on the first day you remember and two pills on the next day. If you forget a pill at any time during your cycle, you should use a backup form of contraception (such as condoms) until you finish the pill pack. If you forgot a pill during the first week of a pack, you may need to use emergency contraception to prevent pregnancy. If you take progestin-only pills (instead of the more common combination pill), it is extremely important to take it at the same time every day. Even a few hours off can allow you to become pregnant. If you are not sure what to do if you have missed a pill, or if you want to know whether you need to consider emergency contraception, contact your doctor. Tell them exactly what happened (how many pills you forgot, for how many days, etc.). How you treat missing or forgetting a pill varies depending on the pill you're taking, so contacting your doctor is always a good idea. Use another method of birth control if you are sick and experiencing vomiting or diarrhea because the pill may not stay in your digestive tract long enough to be effective. If you vomit or have diarrhea within four hours of taking a pill, it is likely to be ineffective at protecting from pregnancy. Use a backup form of birth control just as you would for a missed pill. If you suffer from an eating disorder and use vomiting or laxatives, an oral contraceptive is unlikely to be effective. Use a backup form of contraception. Consult with your doctor or a mental health professional for help.

Try not to ever miss pills, but compensate if you do. Contact your doctor. Consider alternative options when you're sick.
