OPK test help

Deanna

So I’ve never tracked ovulation due to pcos and irregular periods but I’m trying for baby #2. I’ve been on keto for 1 and 1/2 months now and got a period 8/7 to 8/15. I was supposed to start 9/9 but nothing yet. I don’t know if today would be cycle day 36 or cycle day 3 even though I haven’t started my period. I’m gonna keep testing but I just don’t know what day of the cycle it is. I’ve also took an hcg test and negative 😪😪
