I wanted to add that I am 14 weeks, and still having trouble actually feeling my uterus, which apparantly I am supposed to be able to. Like I said if the test is negative make sure that you see a doctor if the symptoms persist because you dont want to let an infection get out of control. Good luck : )
There is no way to tell if you are pregnant based on that description, the only way is to take a test. You could be pregnant, but it could be any number of other things too. You could have a bladder infection, etc. You need to take a pregnancy test, and then see a doctor.
