Question
my ultrasound was on june 1st.i was about 5 months pregnant. another think if my due date is on oct 22 then when did i conceived.my last period was jan.15  

Answer
Mayra,


Ultrasounds done after 12 weeks of pregnancy become less and less accurate, which means that early ultrasounds are the most reliable and would explain why ultrasound results and your doctor's due date  no longer match.  Unless the dates given are more than 2 weeks apart, then your original due date should not be changed.


Based on your last period and due date, you most likely conceived around January 29th.


Best,
Catherine
