Wait a few days and take it first pee, good luck. Sometimes it takes for those hormones to get strong enough.
With this pregnancy it took forever before it turned positive, I think I was two weeks late depends on hormone levels maybe you ovualtrd later than you think etc. I would wait a few more days and take it again and then call the doctor if you're still getting a neg result
Take another pregnancy test. Not sure when you took the first one but wait a few days and try again. Make sure you take the pregnancy test first thing in the morning with your first morning pee. That will give you the most accurate results. Good luck!
You can always call your doctor and request a blood test.
