First ultrasound

M

So i had my first us at 4weeks to confirm I'm pregnant, we could see a gestational sac but the doctor said it was positioned far to the left of uterus when it should be in the center of it! She said we're going to wait and see if it grows and moves toward the center. My next ultrasound is in 2weeks so we shall see, but i'm really worried, is it a dangerous thing? And since it's my first pregnancy i have no clue.. What do you guys think? Has anyone of you been in a similar situation and how did it go? Any help and thoughts are really needed and appreciated! đź’•
