CD42 BFN, is there still a possibility?

Hi everyone!

My (last five) cycles have been 33, 33, 30, 27, and 32 last month. That averages to 31. My LMP was Jan 8, so I was expecting AF between Feb 8 and 10, but today is exactly six weeks since my LMP and HPT showed BFN.

I don’t chart BBT and ovulation days, so I don’t have the data.

My last and unprotected sex was on Feb 1. Did I test too early since it has only been 17 days since?

When should I test for the maximum accuracy?

Feel free to share your experience 🙂

Thank you!
