Hmm should I be testing ?

According to Glow im supposed to be on my second day of AF but I'm not even spotting. I do have mild cramps that come and go but I have been having mild cramps that come and ago since last week. Should I be testing!??? Or maybe I should wait until next week I mean apps aren't 100% accurate. I don't want to test and find a BFN and get all disappointed. I need opinions my fellow TTC ladies !! 😰😰😁
