Three days late👶🏻

my boyfriend and I have been trying to get pregnant for about 5 months now, and according to Glow, I was suppose to get my period on the 5th I tested last night on a cheap dollar store test and it came back negative. I also have a large amount of thick discharge and I have been crampy the last few days & what I believe to be symptoms of pregnancy the last week or two. any chance of pregnancy?
