Im 5 dpo today and take my bbt every morning. This is my first month temping and using opk's but been ttc since a MMC last June. (Today is my due date).
Anyway, my temp has been high since ovulation 5 days ago but today it took a huge drop, a drop of 1.12 degrees. It looks so sharp on the chart! Why would this be? I didn't do anything different this morning. The only thing slightly different was that when I got up after taking It, I had a real dose of diahorrea (sorry tmi) but i don't think that would have caused such a big temp drop. Any ideas?
