I’ve been TTC for 4+ years and am 33yo. In past months I have had slight changes from day to day and a predictable dip and rise at ovulation with positive OPK every month. But this month is a different story. My BBT has been almost completely steady with many days in a row with the exact same temp. I had a positive OPK two days ago in line with a small dip but my temp is just back to the flat line now.... has anyone else experienced this kind of “abnormal regularity” of temperature? Bonus for any info that might be related to thyroid problems or thyroid medication - I started synthroid medication in Early January.

I have scoured others’ charts and googled everything I can think of and cannot find any information or help so thank you in advance for your comments! This month’s chart first and previous month’s chart second for comparison.
