If I got a bfp on 26th Oct what's the earliest I could have conceived for it to show positive? I went by my period date of 20th Sept and was dd 26th June. Went for scan thinking 12 weeks but put me back to 10.5 and cmtoo small for all measurements etc so 're booked for today. Today I go thinking j should be 14.6 with their scab date and they put me back another 4 days. So now due date is 1th July.
They could only do head measurement as baby too big for length so how accurate do we think this is? Thanks
