Please tell me this is negative 😶

This is a negative right? I think I see a faint line, but I know indent lines are sometimes a thing. We literally only had sex once this passed month on the 16th, and he didn't even get close to finishing, but he didn't use a condom for the like 3 seconds before we were interrupted and stopped. Please tell me this is a negative. My expected period is on Thursday, but I've felt nauseous the last 2 days, which was my first symptom with my LO, hence the test. My last period was July 28- August 1.
