How long after LH surge do you ovulate?

Ovulation is considered to occur 28-36 hours after the beginning of the LH rise or 8-20 hours after the LH peak. Daily assessment of the preovular rise in estrogen reflects Graafian follicle development but the rise is less distinct and spread over 3-4 days with marked day to day fluctuations.

When should I take my LH ovulation test?

To get the most accurate reading, you’ll want to:

  1. Use an ovulation test strip between 12 p.m. and 8 p.m. Most women have a surge in LH in the morning, and those levels can be picked up in your urine about four hours later.
  2. Make sure your urine is concentrated enough.
  3. Follow the package directions carefully.

Do LH strips detect ovulation?

How to test ovulation. Ovulation test strips are designed to detect levels of luteinizing hormone (LH) in your urine. This hormone signals ovulation, which is the release of an egg from your ovaries into the fallopian tube.

What should a positive ovulation test strip look like?

Ovulation test kits have two lines: One is the control line that signals the test is working properly while the other is the test line. This line will be lighter or darker than the control line, depending on whether you’re ovulating. The test line appears lighter when you have a low level of LH in your body.

Can you ovulate the same day as LH surge?

The LH surge indicates ovulation will occur at some point within the next twelve to forty-eight hours (on average). The window is large because it is different for everyone. Some people ovulate the same day as the LH surge and some ovulate two days after the surge.

How do I read my LH results?

Positive LH test: The test line (to the left) is as strong as the control line (to the right). You can add this as a positive into the app. Negative LH test: The test line is weak. You should take another test a couple of hours later, at least 2h later, and minimize the intake of fluids during this time.

Does LH surge happen morning or night?

The LH surge triggers the egg to fully mature and to be released from the follicle. A study of 155 cycles from 35 women demonstrated that the onset of the LH surge primarily occurs between midnight and early morning (37% between 00:00 and 04:00, 48% between 04:00 and 08:00).

Can I get pregnant 2 days after LH surge?
