Summarize this article in one sentence.
With these tests, you check your own urine for an increase in the luteinizing hormone (LH). Because this is the hormone that tells your ovary to drop the egg, checking for a rise tells you when you're ovulating.  You can find these tests at drug stores, though your doctor might provide you with one, as well. Start testing 11 days after you started your last period. The kit comes with about a week's worth of sticks that you must use to test your urine once a day. You can either hold the stick will you pee on it or pee into a sterile container, then dip the stick in. The test will tell you what color the stick should turn to indicate an increase in the hormone. Another option is having your doctor monitor your ovulation through regularly scheduled appointments. Your doctor will do a transvaginal ultrasound, which lets the doctor see when you are ovulating. Your doctor will be looking for what is called a dominant follicle. This is a cyst on the ovary that is large enough for an egg to develop inside of.  For this test, you may need an injection of human chorionic gonadotropin (HCG). This drug can help you ovulate, so that you can be inseminated at the correct time. Once you show you are ovulating or about to ovulate, it's time to schedule your appointment. Your doctor should have already let you know how and when to schedule your appointment following ovulation. If you're being impregnated with your partner's sperm, he's going to need to come into the clinic and be able to produce on command. If you're not using your partner's sperm, the clinic should have the sperm you've chosen ready when you're ready. Sperm is usually chosen from a sperm bank and they will send the sperm directly to the clinic.  After your partner produces sperm, it will need to be "washed." Basically, they are separating the best sperm from the dead sperm, as well as washing off the seminal fluid, which shouldn't go directly into the uterus. Some women experience cramping and/or spotting after the procedure is over, which quickly lessens or goes away completely. Some women may continue to experience mild cramping for a day or two after the procedure along with some light vaginal spotting. Try to relax and take it easy the day of the IUI.  You can go about your usual activities the day after the IUI.
Use an at-home ovulation monitoring kit. Consider letting your doctor monitor you, as well. Schedule your appointment. Don't forget the sperm. Expect some cramping and spotting.
