Frequent question: Is BBT accurate for ovulation?

Using a BBT chart is safe, simple and inexpensive. But it’s not necessarily the best method for tracking your ovulation. With an accuracy rate of 76 to 88 percent, BBT charts are considerably less reliable than ovulation test strips.

How accurate is temperature for ovulation?

Track your temperature readings.

Basal body temperature may increase slightly — typically less than a 1/2 degree F (0.3 C) — when you ovulate. Ovulation has likely occurred when the slightly higher temperature remains steady for three days or more.

What is a good BBT for ovulation?

Before ovulation, a woman’s BBT averages between 97°F (36.1°C) and 97.5°F (36.4°C). After ovulation, it rises to 97.6°F (36.4°C) to 98.6°F (37°C). You can track your cycle by taking your BBT every morning.

Does BBT always predict ovulation?

Why track basal body temperature? Tracking BBT with Clue can help make your predictions more accurate. BBT is used by Clue to assess when ovulation has occurred. However, BBT alone cannot predict when ovulation will occur in the future.

Can you ovulate without a rise in BBT?

BBT thermometers are not 100 percent accurate, and some women ovulate even without an increase in temperature. False readings can be caused by a variety of things, including waking up at different times in the morning.

Why is my BBT high before ovulation?

Your basal body temperature changes based on a number of factors, including your hormones. When you ovulate, the hormone progesterone causes your temp to rise. 1 It remains higher throughout the two-week wait. Then, just before your period starts, the hormone progesterone drops.

Can you be pregnant with low BBT?

While you’re more likely to see a one-day temperature drop if you’re pregnant, it’s not a definitive sign of being pregnant. You might see a small dip on your chart almost every month on the seventh or eighth day after you ovulate.

What will BBT be if pregnant?

After the female egg cell is released at ovulation, BBT increases to between 97.6°F (36.4°C) and 98.6°F (37°C). Basal body temperature will drop again if pregnancy doesn’t happen. This temperature drop causes the uterus lining to shed, causing a period to start, and a new menstrual cycle to begin.

Why did my BBT drop after ovulation?

If temperature rises adequately at ovulation time, but then drops dramatically about one week after ovulation (and rises again to a stable temperature), this is typically due to a surge of estrogen in the luteal phase (See Figure 2.5).

How long does BBT stay elevated if pregnant?

Waking or Basal Body Temperature (BBT)

After ovulation, your temperature usually remains elevated until your next period, about two weeks later. But if you become pregnant, it remains high for more than 18 days.

How long does it take for BBT to rise after ovulation?

It can take up to three days after ovulation for the temperature to rise. However, in our experience most women experience temperature rises on the same day or a day later than when an ovulation predictor kit turns positive.
