Well your symptoms are definitely similar to those that come with pregnancy but if the tests have all been negative there is a chance your period may just be very late for some reason.
I remember speaking to my friend on the phone and just mentioning that my boobs were SO sore and she said straight away "You're pregnant". I was trying so hoped she was right and she was but it could have just been regular menstrual pain
Also the peeing thing could be an infection as (and I could be wrong) I believe that it's later on in pregnancy that the constant peeing starts due to increased weight of the uterus on the bladder.
Don't worry, just give it until your next period is due and if that doesn't start do another home test or see your gp.
But make sure you follow the test instructions carefully.
Whatever the outcome, I hope it's the one you want.
