So ive been reading about a lot of moms having an ultrasound done as early as 5 weeks and finding twins. Why did you end up getting an ultra sound so early. I just got my bfp yesterday I would not be very far along somewhere between 3 and 4 weeks based on intercourse but 5 weeks by my first day of last period. When I tested I got a line immediately and it was way darker than the control line do you think they will want me to get an ultrasound because of that? This is my second pregnancy also.
