BBT Chart Vets - Need input again! :)

I had a slight dip in my temp yesterday (4 DPO) and then it shot up like crazy today (5 DPO)...it's too early for an implantation dip/triphasic temps, isn't it?

This is my first month charting so I was wondering if anyone had insight. It will be interesting to see if they stay elevated tomorrow. I kind of panicked and thought what if what I thought was O on 2/2...really wasn't (especially since O on CD 18 is actually early for me)?? I have such a love/hate relationship with all of this micro-managing of my fertility :)

The only other thing I can think of is that my throat is a little scratchy today...so maybe I'm just getting sick, thus the temp spike??

I'll try to attach my chart...

Hi babygirl, sorry for missing this...any update? It looks to me like you O'd on CD18, and that ever-so-slight dip isn't an implantation dip. Don't worry about that anyway, FF says 30% of people that ARE pg get a dip and 20% of woman that AREN'T get a dip...lol.
