Should i take a test or am i over thinking ?

Bebe

So 2 or 3 weeks back me and my boyfriend took a pregnancy test it came out negative but we didn’t read the instruction and we did it wrong so we where gonna take another on but never did. My period was two days late Nd only lasted two days Nd half Nd it was light red the first day Nd black the second day now its gone. Is it possible that i could be pregnant?
