Ultrasound at 4 weeks 4 days

Pj`s mama • DUE DATE : 1-4-16 👶🏻 Preston James
My Dr is sending me for an ultrasound next Friday. I will be 4 weeks and 4 days. I called and asked if this was too early because everything I've read shows that it's too early for something to be seen at 4 weeks and 4 days. I have not had any MC's or bleeding, etc. Which could be a reason why a dr would do one so soon. I happened to have a dr appt the day I got my BFP (last Monday 5/4) and my Dr told me I was probably about 21 days at the time. My due date is Jan 8, 2016 because they still go by the first day of your last period. This app says I am over 5 weeks now due to the fact I put in my due date. Any ideas if I will actually see something at 4 Wks 4 days next fri when I go for the ultrasound? Also my HCG levels on 5/5 was 725 and on 5/7 it did Atleast double at 1596.
