Got an important question about my PREGNANCY! please HELP!!!?

According to your last period you are probably around 6 weeks m/l. It really doesn't matter what date you gave the doctor, they will measure the baby and go off the size of the baby to determine due date and how far long you are. You can get pregnant anytime so it doesn't really matter when your period was. They should be able to see more of the baby when you go back. With my daughter you couldn't hardly see anything with my first ultrasound. Good luck, try to enjoy your pregnancy and not worry so much. And Congratulations!!
