Am I pregnant?

Okay soo, me and my husband tried to conceive July 27th and every day after that for like 4 days straight. I was supposed to start my period on August 5th but instead I kept having discharge which usually never happens unless i am ovulating. Yesterday (August 7th) i went to the bathroom and there was a tint of blood but not my normal full on period like usual. I wore a tampon and when I took it out there was nothing but a light tint of blood. I feel crampy but now I am on day 4 of missed period. I took a test August 6th and it was negative. Please let me know what y’all think. This is our first try.
