Why implantation dip

When charting body temperature, it can be a little confusing figuring out why temperature rises and falls. So, if you see what looks like an implementation dip, your drop in temperature could be due to some other biological event occurring. Conversely, you may have identified an implantation dip on your fertility chart, but still not be pregnant.

The best way to get a more accurate understanding of the reasons behind temperature fluctuations is to look at the larger pattern rather than a singular event. So, when both pregnancy and an implantation dip occur, progesterone will also cause it to rise again. While it is common to get a big, fat positive BFP result just 24 hours after an implantation dip, it could take 48 hours for the hormone levels to show on an at-home urine test. While it would be nice to have a clear sign that you are pregnant based on a positive reading of your basal temperature chart, you are setting your expectations too high.

Think of your chart as showing statistical possibilities rather than an exact way to pinpoint the exact time of ovulation. You can increase your chances of getting a more accurate statistical readout if you combine charting your basal body temperature with the use of an ovulation predictor kit, which is a home test kit to help women better understand their fertile days. In fact, the notion of the basal body temperature rising within a day of ovulation is just an educated guess. Many women, for example, discover that basal body temperature does not rise until two days after ovulation.

The efficacy of basal body temperature depends on how well a woman monitors her temperature and it is usually the most effective before she has her first child. For your best chance of success with this method, be sure to take your temperature before you get out of bed in the morning. Next, get a basal body temperature thermometer. There are numerous signs and symptoms of early pregnancy :.

However, many of these signs and symptoms could be caused by other factors, such as Illness, stress, shift work, jet lag, insomnia, medications, food allergies, alcoholic beverages, or gynecological disorders. Signs and symptoms should not be considered irrefutable evidence. Still, the more you have of them, the more likely you are to be pregnant. Charting your basal body temperature can work but you need to be diligent about how methodically you take your temperature.

If, for instance, you take it first thing in the morning before you get out of bed, it is more likely to be more accurate than if you moved around a bit before taking it. Besides being diligent about how you measure, you should also be careful about how you interpret your records.

Usually, the most accurate interpretations are based on the length of time charting. The more months of history you have in your chart, the more changes in your temperature will be noticeable.

However, you should only use this fertility awareness method if you are diligent about charting your temperature regularly. So, what exactly do you have to do to chart properly? What steps should you take? Where do you even begin? Using your basal body temperature to predict fertility can help you figure out the best days to have sexual intercourse.

It can also tell you with reasonable accuracy if you are pregnant. Detecting early pregnancy may be as simple as noticing a slight dip followed by a rise in basal body temperature after ovulation for a period lasting 18 days or more. While the implantation dip method offers a good way of tracking, the sympto-thermal method might be even better for you. What best describes you? We have a free pregnancy course to help you.

The dip appears during the luteal phase of your cycle—the time between ovulation and your expected period. Implantation of an embryo usually occurs between days seven and 11 of the luteal phase. Despite its name, it's not clear if embryo implantation causes a temporary drop in basal body temperature.

Non-pregnancy charts can also have the dip, which would mean that the phenomenon is not exclusive to pregnancy. One theory is that the hormone estrogen causes the dip. Estrogen peaks twice during your cycle. The first and biggest surge occurs just before ovulation and leads to fertile cervical mucus and a boost in sexual desire.

There is a second surge about midway through the luteal phase after ovulation and before your next expected period. The hormone progesterone raises your body temperature, while estrogen has a counter effect it lowers your temperature.

Estrogen levels are also higher in women who are pregnant. However, even non-pregnant women get the secondary estrogen surge during the luteal phase, which is why the dip also appears on non-pregnancy charts.

Some women also notice a dip the day before they ovulate, which is likely caused by the primary estrogen surge that comes just before ovulation. A free fertility charting app called Fertility Friend did an informal analysis of its users' BBT charts to see if an implantation dip could indicate pregnancy.

While the statistical analysis of just over , BBT charts doesn't qualify as a scientific study, the results were still interesting. The analysis reviewed the charts of both pregnant and non-pregnant women looking for:. Looking at their statistics, twice as many of the pregnancy charts showed an implantation dip. In the informal chart analysis, most women who were pregnant didn't get a dip; the dip more often appeared on non-pregnancy charts.

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. Seeing an implantation dip on your BBT chart is more likely when you are pregnant, but it is not a reliable sign of pregnancy.

Your basal body temperature chart can't tell you with any degree of certainty if you're pregnant—you'll need to take a pregnancy test to know for sure.
