am I out this month?

Is my chart suggesting that I'm going to be due af soon? With the slow decrease in temps? I usually have some cramping when period is on her way but Iv not had anything at all this month, no niggles or mild cramping or anything and my boobs don't hurt as much as I normally get as my usual pms symptoms. Not wanting to waste a test if this looks like I'm going to be coming on... 😩
