Clomid cycle/ spotting

Patricia • Married to my lovely hubs. Baby no.1 is currently downloading. Should be here early October.
Hi all I started cycle 1 of clomid don't ng my last period (30th Dec -4th Jan). Glow says my fertility week was 10th Jan- 16th Jan. My period should have started today according to clomid. Last night I had some bright red blood when I wiped but today no period just ewcm. I tested on Mon 25th and got a negative. Will wait another week before testing again as may just be late due to clomid.
