Update: Spotting Has Continued

So day 15/30 in my cycle. Fertile week. Took an ovulation test yesterday came back negative. My last period was really light and only lasted 3 days. Possibly a faint positive on hpt. Tta currently due to a miscarriage last September. We always use male condoms. And haven't had any break recently. The spotting is now brown but was pink yesterday and I have never had any spotting. Should I take another hpt? Should I take another ovulation test today? Any advice would be helpful.

Update: Second ovulation test saying negative and today should be my peak.
