Need Advice

Hey everyone so this could be a real stupid question but I’m just so nervous that I need some advice or even thoughts.

So the days marked on the Calendar with crowns are the days that I had unprotected sex and are also the days in which my boyfriend came inside me. I have not taken any plan B and my next period isn’t until about another week.

I started feeling some pain yesterday on my lower left side it was kinda sharp and kinda dull at the same time but it’s finally left.

I guess I just want to hear people’s thoughts is it positive or is there a chance I’m not. Should I wait to take a test.
