Glow originally predicted that I would ovulate on 10/6 and my period would be due today....however I overrode that to change it to 10/8 because I had a ton of ewcm and I think I likely ovulated closer to the 8th.

I took a test yesterday and it was negative. In one pic there looks like a line (where the blow arrow points) but later the line was gone so I'm guessing it was nothing.

When would be the right time to test? I'm using frer tests. If my test was negative at 10dpo; will it likely be negative regardless of when I test or is it still possible to get a positive this week?
