Can implantation dip temperatures drop for 2 days consecutively

[foryou62425]

Hi..

I am new to BBT charting I am at 7 dpo, can you guys please have a look at my bbt chart and see that if implantation dip temperatures can drop for 2 days consecutively. I really need some insight. I searched online and some BFP chart shows temp dip below coverline but just for 1 day. Am i out of this?

It's on imgur+.com+/+pb4C1lv (Remove plus sign as i cannot post a link to my chart)

Thanks a lot...
