Should I bother testing?

My period is usually right on time, but 3 or 4 months ago I was convinced I was pregnant because it was five days late. AF eventually came and I was pretty surprised. I had tested with negatives but I wasn't convinced til AF came. 
Anyway I've had a couple of normal periods but this month, I'm two days late with mild cramping and sore breasts and there is a massive chance we could have conceived 
But I had all these symptoms last time so I feel like maybe I'm not? 
I mean I know I should just test lol but should I wait and see a few more days or should I get a test tonight for the morning?
