When determining how long you have been pregnant you count the first day of your LMP. By the time you miss your first period, you will be 4 wks pregnant.

No, you count back 38 weeks for the conception date, but don't forget this is just an estimate.

Get the calendar out on that one and count 40 weeks back

if you are 21 weeks pregnant when was conception?

To calculate conception you can go from the first day of your last period and add two weeks eg if your last period was on the first of the month then conception would have taken place at around the 15th . If you do not no the first day of your last period but no how many weeks pregnant you are then count back and minus two weeks eg if you are seventeen weeks on the 2nd of September go back on the calendar 15 weeks this will give you a approximate conception date

count 11 weeks back from April 26 and that will be your date of conception

Count back 2 weeks, so 6 weeks and 4 days old. Count back 6 weeks and 4 days old on a calendar and that would be an estimate. Also, check out, and put in you're due date or you're last LMP and they can tell you an estimate of conception. God Bless

Count out ~260 days (37 - 38 weeks) from conception to get rough delivery date.

u will skip ur period two weeks after conception and ur pregnancy test will be positive two weeks after conception

They count the weeks of pregnancy back to the last date of the first day of your menstrual period, not to date of conception. For example, I am considered to be at 15 weeks. The first day of my last period was 11/25/08 and the date of conception was anywhere between 12/9 and 12/16

Pregnancy supposedly (medically) lasts for 40 weeks. In reality it lasts for 38 weeks from conception. Conception occurs approximately 14 days after your last period started for a woman who has a 28 day cycle. So everyone's pregnancy is based on these mythical 14 days eventhough very few women have a 28 day cycle! Medically they count these 14 days within the 40 weeks you are pregnant. You are considered 2 weeks pregnant at the moment of conception! Therefore three weeks after "The Deed" you are considered 5 weeks pregnant. Your doctor will not really care when you fell pregnant, s/he will be more concerned about the date of your last period and count from there.

a month and 1 weekA Month & a weekRoughly 1 month pregnantFive weeks from conception or five weeks from lmp? If its five weeks from lmp you would be one month and one week. If you know you are exactly five weeks from conception you would be considered about 7 weeks because the doctors count from your lmp which would be about two weeks before you conceived. Either way - good luck.

Erm ... 20 weeks and four days ago ... Dohh!! Look at a calendar and count backwards 20 weeks, then backwards 4 days - there is your estimated date of conception.

if u are 20 weeks lmp you got pregnant 18 weeks ago so count back 18 weeks but if u want a date u need to give due date or lmp

You always get symptoms at least three weeks after conception (like puking, nausea and hunger)

It depends if you were five weeks pregnant or five weeks from conception. If five weeks pregnant you conceived around 18 May, if five weeks from conception you conceived around 4 May. If you could see a heartbeat you were 5 weeks from conception.

You start missing periods as soon as you are pregnant. So if your period was due in two weeks or three weeks from conception - it won't happen.

I am guessing you mean that you want to know your date of conception? It really depends on a couple of factors. If your normal periods are regular, you can be fairly accurate with conception date within a couple of days. Count back 14 days from when your period was DUE (ie but didn't come because you were pregnant) and this will be around the time of conception. Conception date will be within two days either side of this date. If you are pregnant now, an ultrasound will tell you very accurately what your conception date is. As long as you have an ultrasound within the first 10 weeks - the earlier the better. An experienced ultrasonic person can tell you down to the day - ie six weeks and three days.

The earliest you can take a pregnancy test is 2 weeks after sex. It takes 2 weeks until conception has finished.

The best way to check the date is count 12 to 14 days from the first day of your last period. Conception usually happens then.

If you are nine weeks pregnant, the intercourse you had approximately 7 weeks ago is when you conceived...or count 14 days from the day you started your last period to get your approximate conception date. Note: many people do not ovulate exactly on day 14 of their cycles. It is common anytime from day 10 to day 20. I hope something in here helped!

Three weeks pregnant is a week before you miss a period so it is impossible to know it is twins. If you are three weeks after conception, (5 weeks pregnant)it is still early to see a heartbeat.
