Should I take a test

I have been trying for our second baby for a year and a half. My periods in the past have been very sporadic, but over the last 5 month there has been a patten (within a day, give or take). I was expecting it two days ago. I decided 4 months ago to stop taking tests, as it was just stressing me out and not helping. I’m scared to take a test now (probably, due to the fact I’m worried about disappointment) should I wait longer to see if my period rears its ugly head? Or would you take a test?
