I see a surge in the morning and it is back to none in the afternoon.Updated 6 months ago

Our LH goes up and down very sharply. The entire surge can be done within 24 hours. Therefore, it is very normal that you see a surge in the morning and it is back to none in the afternoon or the next day. Once you see the surge, you are ovulating in 12-48 hours, so it is the best chance to try for a baby. Please make sure you always use the first-morning urine or limit fluid intake for at least 2 hours before each test.
