Fallback rise? Chart question.

Ashleigh • Gave birth to my first on 2/21/15. Lincoln James. 💙
So, FF is saying I ovulated CD 12, which seems right. I took B complex this cycle to lengthen my luteal phase and it brought my ovulation up to CD 12 from CD 15. Which hopefully means I will have a longer LP
BUT, what is this dip on 3 DPO on my chart? Is that a fallback rise possibly? If it is, should my temp rise back up tomorrow? 
 Does this look right? I also never got EWCM, only watery. Which I heard is alright because that also considered fertile CM. Help a girl out!
