I had to test at 14 days after and it came back negative. Then 3 days later it came back positive. But we were trying and using clomid.
Yeah it’s too early especially if you didn’t ovulate till like 5 days after having sex. I’d wait another week or two
well there isn’t a test that is 100% accurate but i would suggest waiting a few weeks before taking another test or you could wait till your next period to be sure whether your pregnant or just not feeling great
