Should I test?

I thought I maybe started my period yesterday. After a day of brown spotting, very light, yesterday it got a little heavier. I wore a tampon but after the 4 hours and taking it out it wasn’t completely full, so I didn’t put another in. Had a super light flow the rest of the day. This morning so far I haven’t seen really anything. I’m 14DPO. My temps aren’t as high as earlier in my luteal phase but they haven’t dropped below coverline (except once on 12DPO when I had the brown spotting). Ovulation has been confirmed through BBT so I know this is about the time I should be starting AF, I’m not seeing the temp drops though.
