Spotting for over a week

Anyone else have this issue around their ovulation period? Glow is quite accurate for me in that regard, tracked using OPKs for almost a year, Glow is pretty accurate save for a day or two sometimes, so I don't track anymore. I monitor my symptoms now to get an idea of when to BD, plus our fertility doctor says we have enough sex to cover the bases.

I started spotting late last week, and then all CM stopped Wednesday morning and assumed I was done ovulating. Wednesday night my husband and I gave it one last go with Conceive Plus (had only received it in the mail Wednesday arvie).

But since Thursday morning, I've been spotting again! It looked like it was EWCM but I assumed that was due to the Conceive Plus. However now it's Saturday morning and I'm STILL SPOTTING.

I don't know whether that's a good or bad sign (relating to my fertility this month, I know it's way too early to be considered pregnancy as I am only due for my period on the 23rd).
