First off, my job requires me to be very active, a few nights ago ((on a very busy night)) I noticed the area where my uterus is was very hard, it hasn't gone away since then. Whenever i cough or sneeze it gets tight and hurts a little. I shouldn't be getting my period for another week or so and my breasts are swollen too (which could easily be from my period being so near). but I have never had this happen before, and i don't want to do nothing, but at the same time i don't want to freak out and get a bunch of tests done and have it be nothing. Help please, any ideas would be a savior.
