hey sis!
don't worry much about it! when i submitted my docs, the bank statement of my hubby doesn't show big savings also, although I've explained it well in the application form, stating that most of his savings were used in his frequent visits, wedding & honeymoon.
aside from that, i have also submitted his 12months/1year payslips, showing good salary, maybe, that helped in approving my visa, hehehe!
good luck!
