@Patrice thanks 😊
I'd go to the doctor to just check.
Try the first response test! I’m on a similar timeline, I had my last period in December and just found out I’m pregnant on Friday. I had similar symptoms. I was using the pregmate tests and they were showing vvfl but the first response reacted right away. They also have tests for before you’re missed period which I think are way more sensitive.
I would say yes you need to go to the doctor and get a blood test done.
