Agree with Ellie- it’s probably a little early and will start rising around CD 11-12. If you are just now starting to track and test, PreMom won’t be as accurate as it needs a couple cycles to really predict.
You will likely not ovulate until cd 14 or later. I ovulate 17,18,19
If your cycle is 28 days you wouldn’t necessarily ovulate until day 14 on a ‘normal’ cycle so I wouldn’t worry too much, my experience is that the tests only start to increase about 48 hours before :) hope that’s helpful x
