What can cause a BBT mid luteal phase dip?

[Bing28]

Hi everyone,

As you can see on my chart I had a dip in my BBT yesterday.

This is my first cycle charting and I know implantation can cause a dip in BBT in the luteal phase, but I'm wondering what other reasons can cause a dip, because I don't want to get my hopes up too much only to be let down!

Any info would be great!
Thanks
Xx

This is what fertility friend says about it:

Out of place temperatures

Both in your pre-ovulation phase and your luteal phase, you may have temperatures that just do not seem to "fit". This is usually nothing to worry about since you are looking for trends over time rather than individual temperatures. Seemingly out of place temperatures can be a fluke or can be caused by any number of factors. A few out of place temperatures can usually be ignored without impacting the interpretation of your chart, especially if they are not close to ovulation. There is generally no need to discard out of place temeratures. FertilityFriend.com's automatic ovulation detector is able to detect ovulation based on the pattern of your chart and all signs, even when some data is not accurate.

Hope that helps & Fx for a BFP!
