Wondfo 40 (LH) Ovulation Tests + 10 (HCG) Pregnancy Test Strip Combo Pack with Collection Cups by USHealthTests
How to use the Ovulation Test:  The length of the menstrual cycle is the duration from your first menstrual bleeding day to the day before the next bleeding begins. Determine the length of menstrual cycle before test. If your cycle is shorter than 21 days or longer than 38 days, consult a physician. If you do not know your cycle length, you may begin the test 11 days after your first period since the average cycle length is 28 days. Perform 1 test each day over a 5 days period, or until the LH surge has been detected. The Pregnancy test: Human chorionic gonadotropin (hCG) is a hormone, produced by the developing placenta shortly after the conception and secreted into the urine. The pregnancy test contains antibodies which specifically react with this hormone. This test detects hCG at a level of 25 mIU/ml.
