So I’m 11 dpo, ovulated cd 15. My LP is 14 days long but today I’ve had a massive temp drop. It’s to early for AF and I’ve read a lot about implantation dips and that they appear on both pregnancy and non pregnancy charts, I’m just looking for any sights really.

I didn’t temp pre ovulation due to Illness and in and out of hospital but I did catch my positive opk so temped from then.
