PVB means per vaginal bleeding, i.e., bleeding through the vagina. Bulky right ovary
indicates that ovulation took place in this ovary and the corpus luteum
that has formed as a result of pregnancy
makes the ovary bulky. There is sometimes a slight lack of correlation of the exact dates and the period of gestation obtained in a sonogram. If you had regular 28-30 day cycles prior to this pregnancy, then you should see if the disparity exists after a repeat scan after about 2 weeks. Also, your bleeding is of utmost importance at this stage and this needs to be taken care of. Please follow your doctor's instructions. Wish you a safe pregnancy.
