I'm worried

Ok so I've been TTC for a while today at work a lady fell and I had to help her get up but she's too heavy and only tried once after I tried my lower back and knees hurt because of problems I have but also my lower abdomen and left side (ovaries) hurt too like a pinching pain I haven't taken a test since I'm waiting to be late on my period of anything 
You'll you guys consider getting one just to be sure it's barely been 6 days after my fertile window
