HPT question

So I have several digital tests in my drawer for after my TWW but now i'm reading from several people that I could be pregnant before they would show anything..what other brand should I get? I want pink dye tests not the blue ones. Also, if my hubby and I had sex on Tuesday at 11pm with preseed when I had flashing smiley, then at 10 am yesterday I got my solid smiley...if we have sex tonight am I still at a very high chance of conceiving? (we unfortunately couldn't BD lastnight)
