BBT drop - 6 days DPO

Kate

My last "peak" OPK reading was Jan 23rd, (I also had one on Jan 22) I'm assuming the 23rd was my ovulation day? Today I had a big drop in BBT. I've only been tracking BBT since mid-month. This is our 2nd cycle TTC...

Any insight of what a drop like this could mean 6 days DPO?

Thanks ladies 💞
