Should I test?

My period was due today but absolutely no sign of it.. I keep thinking I feel blood leaking but instead it’s just discharge. I usually get super sore boobs & terrible cramps but instead nothing. zilch zero. I am extremely gassy & my farts are like trapped at times. I do have to say I don’t “feel pregnant” but this cycle does feel super different lol I hope you understand.

I only had sex 3 times during my fertile window, so

should I test?
