Af acting strange

Ok I don't know if I'm doing this right or if it is in right place but I was hoping for some advise. I have been ttc and this month af was a day late, then it showed for 2 days and left. Normally it lasts about 5 days, it was also much lighter than normal, and it looked differnt too this may be tmi but it is normally really dark red, but not this time. This time it was more strawberry jelly looking, I have also had random symptoms getting really light headed,nauseous, and I am so hungry it's crazy. I know I should just take a test, but I'm tired of the bfn, I just thought if get some opinions here .
