It is recommended to start testing for ovulation 2-3 days before expected ovulation. Ovulation typically occurs 14 days before the start of your menstruation. So if your cycle is 28 days, you should start testing for ovulation on day 11 or 12 (day 1 being the first day of your last menstruation).
If you are unsure about the length of your cycle, it is recommended to start testing on day 10 or 11 of your cycle.
The ovulation test measures the concentration of the ovulation hormone LH (luteinizing hormone).
24-36 hours before ovulation, the LH hormone rises significantly, and if you test with an ovulation test, your ovulation test will be positive when the hormone has risen in connection with your ovulation.
You can recognize the positive ovulation test by the test line being as dark or even darker than the control line.

Pregnancy tests are designed to react to the pregnancy hormone Human Chorionic Gonadotropin, also known as hCG. This hormone increases if a fertilized egg implants in the woman's uterus. Therefore, an elevated hCG level in a woman's urine indicates that she is pregnant.
Pregnancy tests have two antibody lines. One is the control line, which changes color when dipped in urine. If the control line appears with color, you know that your test is functioning correctly. The other line is called the test line, and this line only changes color if your urine contains the amount of pregnancy hormone hCG that your pregnancy test is sensitive to.

Pregnancy tests are of such high quality today that they are more than 99% reliable and accurate from the day of expected menstruation. However, you can still be pregnant even if your pregnancy test is negative. This is especially true if you test before the expected day of menstruation.
In short, a woman's temperature rises by 0.2 to 0.5 degrees Celsius per day after ovulation due to the hormone progesterone. The temperature remains at this elevated level during the latter part of the menstrual cycle until menstruation begins and the woman's cycle starts over again.
This means that if you measure your temperature every day, you will also be able to determine when you are ovulating and have the highest chance of getting pregnant through intercourse or insemination.
