BBT Help?

Hi all,

I was wondering if anyone could help me. I’m not predicted to ovulate until tomorrow (but I never ovulate on time with glow - usually before).

I thought I had already O’d (on cd17) bgiven the temp rise/stability until yesterday’s drop. I did sleep with the fan on that night, where as the rest I hadn’t - I didn’t know if that has an effect on bbt. I’m consistent with taking it at 6am and I always sleep well.

Looking at my chart (I know it’s not a full cycle) would you say I have ovulated already?

Thanks in advance

Oh
