Period length and ovulation

Jamie

Hello 😊

Question- Usually my period is 3 days long and I then ovulate cd 13 or 14 on a 28 day cycle.

This month I took letrozole cd 3-7 and my period lasted until cd 6 twice as long as normal. When your period is a longer will that usually push back your ovulation day as well? It is cd 12 now and my lh tests are still very low and my clear blue digital opks are an empty circle. I know I probably just need to be patient but I was just wondering if it had any correlation.

Thank you
