A member asked:
The ultrasound said 11weeks and 6 days pregnant so when did i conceived? my last lmp was on jan 23 2015
A doctor has provided 1 answer
Around January 7: By LMP, estimate conception date as Feb 6, for 28-day cycles. By ultrasound scan, estimate conception date as Jan 7. In such a case, the U/S scan is correct, which means the January 23rd "period" was not really a normal regular period, but was vaginal bleeding associated with early pregnancy. However, if one had sex ONLY around Feb 6, and not prior to that, one can ask the doctor to check the U/S.
