Question

So as of today I would be 5 weeks and 6 days pregnant be because my last period was june 28th...I took the test yesterday and I thought I saw a VERY faint line (maybe even my imaginiation) my husband however did not see anything and as I was sturggle to show him my supposed line I couldn't even find it anymore🤦🏾‍♀️🤦🏾‍♀️ so my question is that if the test is not showing absolutely positive at this point, should I just rule out being pregnant? My period for the month of july is about 10 days late
