Temp drop below coverline 4dpo?

I've never had this happen before!

I've always had a temp increase on CD 16 or CD 17 and my temps always stayed high until AF came- I've been temping for 4 months now.

Today I'm 4dpo and my temp went a little below the coverline. I was cold this morning- DH stole the blankets but I don't know if that would effect it...any ideas?

I honestly think it's just hovering the coverline. Probably a fallback rise....estrogen can be surging.

I am pretty sure it's just 'random'

Thank you Michelle! I just looked on the internet and it said a dip this can happen at 4dpo sometimes because of a surge of estrogen. Although one site said that implantation can happen as early as 4dpo... we can only dream!!
