Does this look like a possible implantation dip?  This is the first cycle that I have been persistent with temping.  My ovulation dip is right in line with my peak opk so I'm wondering if this looks like an implantation dip?  I've never been that low before.  I've also had lower back pain, crazy vivid dreams last night, yet restless sleep.  Last night I had a random melt down while watching TV with my husband for no reason at all.  I'm really hoping this is a positive sign to my BFP!
