pregnant with blocked tubes

I have blocked tubes, 19yo
This month has been really funny! 
-frequent toilet vists
-car sick
-sore breasts 
-sleepy all the time
-last week lots of white thick discharge 
-this week I feel sick at my throat, earlier an earlier as the days go on 
But the main thing im concered about 
Iast two days I've had bad cramping as if im going to get my period. Two days on, no period! Period is due next week though.
I read online is can be implantation cramps but surely I cannot be pregnant I have blocked tubes but this can be a miracle can't it?
What do you think?
