Should I take test?

I ovulated on cycle day 22 and now it’s cycle day 39 I am 3 days late from my expected periods. I have been feeling that my period is about to come since 5 days. I am scared to take a test as we have been disappointed for 1 and half year. Has anyone experienced similar symptoms and are pregnant. Also I am super hungry as soon as I wake up and all of sudden I feel like my body emits heat. I am scared to get my hopes up and scared to take test and see no line.
