Sounds like the way i normally am around ovulation. It's too early for pregnancy symptoms. Implantation happens at 6dpo at the earliest, and 12dpo at the latest and then it takes a few days for hcg to be detectable. That's why they say to just wait until your period is officially (5+ days) late before testing. Testing too early is a waste of time since you can't know for sure if it's a legit negative or not.

9DPO is also to early to test . Implantion happens normally 6-12DPO and takes a couple of days for hormones to rise I would wait until a few days before your AF

Too early to tell... if you're thinking pregnancy wait to test 4dpo is way too early
