Should I take a test again or wait?

Leanne
Cycle last month was 45 days which wasn't normal for me and this month I am waiting for period and still hasn't come I'm on day 44. 
I don't know if to leave it abit long but what's more worrying is that my cycle is so long. 
We are trying for a baby but I don't like doing test as when they come back negative it hurts😞
