“Late” period?

Hi all,

First off..thank you for taking the time to read this post and offering any advice you may have.

Hubs and I began TTC #1 in March 2018 (stoped the pill March 1) and no luck yet. Since stopping the pill I have had regular periods (in the sense that they are consistent) however, I do have a long cycle. Typically between 41-43 days. AF has not shown this month yet I am on day 47. I took a test on day 43 and it was negative. I am sure it could be a number of factors as to why I could be “late” but when do you think I should retest?

I welcome any advice! 😌
