I see a surge in the morning and it is back to none in the afternoon.Updated 10 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.
