Chart help please!! What is with the huge drop then spike!?

[HisKhaleesi]

First time charting, I ovulated late this month but it looks like my LP is staying in tact in think... I thought I was out yesterday because my temp dropped to the coverline (10DPO), so I was really sad all day yesterday waiting for AF to come, I felt a little crampy and sick. Well this morning it shot up to the highest its been since ovulation. Ive had two little dips but nothing as drastic as that drop and rise. What could this mean?

That drop could have been from implantation. Could be a very good sign if your temps stay up!! Good luck!!

Could be good, could be bad. It can go either way unfortunately. Last cycle I had this same drop and rise and actually if u look at my chart u'll notice it has happened I think every cycle 2-4 days before AF came. If it stays up high over the next few days that could be a good indicator to take a test =) good luck!

Well it didnt stay up so I guess its Af on her way for me.
