You will not have a true period while pregnant. Most women will confuse vaginal bleeding (which you can have) to a period which you can't. As I'm sure you know, every month your uterus prepares for an egg. If it remains unfertilized, you shed this lining and you get your period. If it is fertilized, it will attach to the uterus whch can cause implantation bleeding. Only about 30% of women experiance this, and it will generally be very light an can last for a few hours up to a day or two. If you had a real period while pregnant, you would shed the linin your baby needs to grow on which would result in miscarriage. Your doctor will be the best to see. Some women don't show on urine tests for whatever reasons, and only a blood test can prove they are.
