View real examples of an implantation dip and learn how to read your Basal Body Temperature (BBT) chart to see if you could be pregnant.

For those that chart their basal body temperature (BBT), an implantation dip could be an early indication of pregnancy. As you know, ovulation can be detected on a basal body temperature chart by a slight shift in temperature midway through your cycle. By charting your BBT every day, you can detect the day you ovulate by looking for a slight temperature rise that will remain elevated after ovulation. While with a regular chart, your temps will remain elevated, with an implantation dip, your chart will show a one-day drop in temperature. Claim Your 20 Free Pregnancy Tests – Click Here

What is an implantation dip?

An implantation dip is a luteal phase dip that will typically occur between 7 and 10 days past ovulation (DPO), and is an indication of implantation – an early sign of pregnancy when the fertilized egg implants itself. An implantation dip is an increase in your estrogen hormone so it lowers your temperature creating a dip in your basal body temperature (BBT). For many women, during implantation, they may also experience some spotting around this time called implantation bleeding.

Does an implantation dip mean you’re pregnant?

Here’s a look at my chart. You will notice right here that the temperature goes up during ovulation. Hopefully you can see this and then right here, it shoots back down at 6 DPO and it goes back up. You can see this red line and here’s the dip directly underneath it. So you will notice right here in this chart, they are not pregnant. There is no BFP unfortunately and they did a start a new cycle. But right here, you will notice an increased inner temperature. Ovulation occurred and then they had a major dip right here. This is a perfect picture of an implantation dip. It occurred for them at 6 DPO, six days past ovulation. You could see an implantation dip as early as 6 DPO or as late as 12 DPO. Basically what you are looking for is a dip in your basal body temperature. Now an implantation dip is fairly uncommon for a non-pregnancy chart & will only show up in about 10% of non-pregnant charts.

This is a pregnancy chart, and you will notice the dip occurs right here at 8 DPO at the time of implantation. This is the time that the fertilized egg is implanting itself. Now, an implantation dip only occurs in about 25% of pregnancy charts, while a full 75% of pregnancy charts never show an implantation dip. So you can find it in both charts. However, it is more commonly found in those that are pregnant. So with that said, if you do see one, it’s a great indicator of a possible pregnancy. However, remember you must test with a pregnancy test to be sure.

The bottom line

Now I’ve had three successful births and none of our charts in our four years of trying to conceive have I ever personally had an implantation dip. This is my last chart and you will notice that there is no implantation done, and this is basically what all of my charts look like. But an implantation dip can definitely be one of the early signs of pregnancy, especially when in conjunction with some of the other more common early signs of pregnancy. Do keep in mind though that an implantation dip will not always show in a pregnancy chart, so don’t fret if you don’t have an implantation dip – it doesn’t mean you’re not pregnant. On the other hand, if you do have a dip in your chart, there is the chance that it is still a non-pregnant chart. Only testing will tell for sure.

    I took a positive ovulation test on the 29th and 30th of January. My cycle is usually irregular, but I read that the luteal phase usually lasts around 14 days. I haven’t had started my period, and I’ve had 2 negative pregnancy test, and my bbt is usually 97.1, but today it spiked to 97.9.. I guess my question is, is this normal?
