Basal body temp decreasing 8 DPO??

April B

I ovulated about 8 days ago, and my temp has been deceasing for 3 days in a row (since 6 DPO. It’s too early for AF — I usually don’t see a dip until days 11-14, then my next cycle starts.

Anyone familiar with this or know why this could be happening? I confirmed O on Mar 31 with OPKs and EWCM.

Any help???
