I agree with Heather. It could be a positive sign and definitely isn't a negative sign, but unfortunately with temps even a triphasic temp pattern although promising isn't considered a reliable way to predict pregnancy. Good Luck!
It's hard to say, since you're only 8 dpo...but it definitely could be a good sign! Especially since your temps started dropping at this time last month. If it continues to stay at a higher level, you might have a triphasic chart, which happens more often in pregnancy cycles than in non-pregnancy cycles!
Good luck!!!
I'm correcting this post. Today is 8 dpo, last month on 8 dpo my tempature started to drop. On 10 dpo my AF started. Sorry to confuse you.
