Hello, I have my implanon removed on the 12th may and I've had no bleeding at all and have done a pregnancy test (clear blue) with says I'm 2-3 weeks but on the box it says the doctor will say 4-5 weeks.. what I'm wondering is when do you date the pregnancy from and when would be my estimated due date?

The best doctors in the world can only guess to a 4 week period. Meaning they guess a day with a two week before and two week after window of opportunity.

Primary factor is fetal development... meaning how big it is...

THe only people walking the earth that know the exact day it happened... had an invitro procedure...

Even doing it the old fashioned way... fertilization can occur a week after sex occurs.

If you slept with mor ethan one man that entire month... DNA testing is the only way to establish who the father is.

Thank u for your response but my question was not regarding dna! I have only one partner!

And as we were trying to conceive the date of conception can not be narrowed down to one night.

All I wondered was if someone had expreanced the same thing and how the docs had dated there pregnancy

I told you how they date them... any doctor can only give a 4 week window as to when it actually happened... its impossible for any medical professional to be more specific that that.
