Has anyone ovulated and not gotten a positive ovulation test?

I have been taking ovulation tests since day one of my cycle like the doctor told me and I started doing them 4 times a day after my days 5-9 of clomid and then I started every time I peed hoping maybe I could get a positive sometime. Currently I’m on cycle day 24 and haven’t gotten a positive. I started having pale pink spotting yesterday and a little today and I only seen it like 3 times when I wiped. My friend thought it was like implantation spotting but I never got a positive opk.. I’m afraid it’s just a start of a period and I’m out this month 😔 any input from anyone??
