Is this considered an Ovulation dip in temp?

[youngmommy26]

Hey ladies, so my OPK is almost positive, I should be ovulating tomarrow, having tons of EWCM, cervix is high and very soft, having cramping too, I noticed this morning my temp went lower than my lowest temp so far, so is this the dip people talk about? This is my first month temping, so I wasn't sure how this works. Any help would be appreciated! Also how long will I have this dip in temp before it spikes?
