Pregnant straight after a miscarriage

On the 22nd June 2015 I miscarriaged at 4weeks+3 and me and my partner tried again straight away. 
I started feel all the signs again and did loads of tests two weeks before me period was due and they were all negative then the day of my period didn't come I did a test and it was positive 22nd July and then did a clear blue test on the 24th and it was '2-3 weeks pregnant' 
We are both over the moon it happened so quickly.
Going Drs tomorrow to confirm the pregnancy!
