I'm not really sure! I went back and looked at my chart again and i'm pretty sure that I ovulated on cd21 which would make me only 6dpo.
Last cycle I had a bloated, felt like gas pains in my lower abdomen all day and I had a headache for a few days before that along with watery cm before I got my bfp the following day 12dpo
this cycle last night my headache started, still here today, and now i'm getting like pinching pains on my left side which is the side i ovulated from. I've also had watery cm yesterday and a little today. So i'm hoping i'm implanting today and tomorrow I'll start seeing something.
As for those blue tests I still dont know what to think about them. They gave me positives when they were indeed positive and negatives when they should have been negative up until after I ovulated. So maybe it detects the hormone that is put off by a fertilized egg before it implants?
Anyway.. idk, but that is what i'm going with for now
