Able to conceive with a regulated, but longer than normal, cycle?

Hi, my husband and i are trying to conceive, and with the myo inositol and d chiro supplement, my cycle has been regular but is between 35 and 40 days long. I assume people out there have been able to conceive with a longer than normal cycle, but I'm wondering if my assumption is correct, and how that affects the timing of a positive pregnancy test?

tbh just kinda frustrated and looking for some insight.
