Late period and I’m afraid to test, 34 day cycle on letrozole

So my period is late I’m on day 34, been on letrozole for 5 m and my cycle is always 28-30 days. I had one 32 day cycle but that’s rare. Now going on day 34 and I am waiting a few more days to test. I’ve never skipped a period or had one longer than 32 day cycle

I’m pretty sure based on temp on my ovulation day

I’m waiting to test because I do feel like I normally do before my period and have had some light spotting.

Anyone else have this happen while on meds?
