So i'm a week late. My last sexual activity was January 22 & February 5. both condom WITH pull out (i gave him a bj then he came on my chest)

I tested this afternoon since alot have told me a test would be accurate by now. It shows negative. But everytime I put it in the light, it does show a slight indent line. I'm trying not to panic but should I just lay down the test? This test is very cheap.
