Longer lp/late af

Since forever my lp has been 14 days.

My 2nd cycle of femara I didn’t get period until 19 dpo, my temp didn’t drop either.

This cycle I took off from meds. Today is 17 dpo!! I doubt I’m pregnant. My temp was below cover today.

Google has nothing. I have always been able to count on my chart. It has never failed me. This drives me crazy & I hate how my hopes get up when af is late 😔
