How accurately can a...

How accurately can a doctor predict the conception date within the first four weeks, before an ultrasound?

Doctor's Assistant: When was your last pap smear? Have you ever had an irregular pap?

I am the potential father, so I do not know that answer. My partner had intercourse with someone else two weeks after me, and the doctor predicts the other person is the father. I am just wondering if he could be off by two weeks in that prediction.

Doctor's Assistant: Is this your first time reaching out for information about this? In general, how would you describe your overall health?

Yes, my health is very good.

Calculating the date of conception by LMP during early pregnancy is an estimate and can be off two weeks so i would recommend you to wait for an ultrasound as date of conception is most accurate during early pregnancy ultrasound specially between 8 to 18 weeks time period.

Hope this helps.
