Please be honest...

My bbt has stayed consistently high since ovulation, and I've been pretty excited about it until today... My temp had a drastic drop and now I'm wondering if I'm out this month. I took a test today and it looked pretty stinkin negative to me... But someone said that my drop could be an implantation drop! I am new to charting my bbt, do you think that my drop today could be from implantation? Please be honest!!!! (Of course, I will continue to chart) Thank you lovely ladies, and baby dust! 💜
