Any opinions ?👀

It just came to my mind that my last period(in July) might have been spotting instead 🤔. It was the lightest period I’ve ever had and only lasted no more than 3 days and now my August period is about 3 weeks late now, but I’ve been getting cramps like my period is about to come but then it disappears a few minutes later. I am going to take a test this weekend. Did anyone else go through this before?
