Pregnancy after Miscarriage?

So my husband and I had a miscarriage on June 12. I bled for about 5 days. Given the go ahead to have after a week we did. I had a loss of all symotoms and had sever tests verifying there was no more hcg, no fetal matter left. I was also told my body bounces back from things that would out down most. About another week and a half later I started having tender breasts. I thought it was a period sign but each day they got more painful to the point clothes even hurt. Also fatigue and frequent urination followed. Out of curiosity I took 3 hpts all faint positives. This was before the due date of my expected Period. Tuesday was the day it should've been here but I missed, still with a continuing of overly sore sensitive, tingling and tender breasts, increasing exhaustion, increase in appetite and urination and moodiness. We both believe its another pregnancy and are crossing fingers. Anyone had this happen before or know anything about situations like mine.?
