Equate test accurate??

Amber • 28 yrs old-married for 8 years. Lovebug born 11/3/09 BFP after miscarriage and before AF. Due end of August
I miscarried on 11/9 and never had a period. I had gotten numerous hcg neg tests and levels followed down. Out of curiosity I bought a test today because I have yet to have a period and had normal 26 day cycles. Are these tests reliable? Could that be an evap line?
