Is it me or...

Okay so a day or two after my AF ended i started cramping for a couple of days and had light spotting. BUT i didnt have alot of discharge like i normally would during ovulation. Did i ovulate or is that possible?? According to the app and my calculations im supposed to ovulate on the 7th and my fertile window starts tomorrow... Im very excited because i bought the Pre Seed lub for this cycle but would it even be a point in using it if i already had my big O day??
