Three day temp dip at 6dpo???

[getoffmycloud]

Hiya, this is my first post on this site. Just wondered if you ladies could help me with a temping query. I had quite a big temp (although not below the coverline)at 6dpo and it stayed that way for 7dpo and 8dpo, but today at 9dpo it shot right up again. I know a temp dip can indicate implantation, which of course I'm hoping for, but has anyone heard of a three day temp dip that was implantation?
Thank you ladies for your help xxx

I don't think an implantation dip could last 3 days. Are you definitely sure you ovulated?

yes definitely ovulated, confirmed with temps, opks and CBFM. Very strange. I can't find anything on the web that someone has had a similar situation. One lady I read about had a two day dip and was expecting twins

Have you done temps in previous months? Are your temps anythinng like these? Three day dip is not implantation. Could be a number of other things, but just wondering whether the temps are similar to previous months for you?
