Yes, technically your first week of pregnancy is the week of your last period which is odd because you haven't even conceived yet! Welcome to the wonder world where mathematics and pregnancy don't mix and you somehow squeeze 40 weeks into 9 months?! By the time you actually find out you are pregnant you are generally 4 weeks along because the 4th weeks is the week you would generally miss your expected period.
Conception is when sperm meets egg and they attach to the wall of your uterus and become an embryo. It's essentially the day you got pregnant.
It can happen up to 48 hours after sex.
This can be confusing! The first week of pregnancy is actually considered to be the day of your last menstrual period, before you are technically even pregnant! You are actually two weeks pregnant when conception occurs, and generally four weeks pregnant before you can get a positive pregnancy test!
Nothing. You're considered 2 weeks pregnant before you even have sex. The 1st day of your period is the start of week one and the best time to get pregnant in a 28 day cycle is around day 14. As the pregnancy calendar goes from the 1st day of the last period you're considered 2 weeks pregnant before conception takes place.
No, not necessarily. How far along you are is estimated based on the first day of your last menstrual cycle. For example, if you just missed your period, then you're probably already 4 weeks pregnant!
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
Nine weeks before that, which is the same as two weeks after your last menstrual period. Doctors include the two weeks before conception in their calculation of the pregnancy date; that is, they start the calculation from the first day of your last period. Approximately 10/31/09.
Erm....11 weeks and 4 days before June 29th maybe??? Like the 4th April?
The day after conception or the day after sex? I know they may sound the same but they are very different. Conception would mean you know you got pregnant that very day. If you had sex and had a period the next day chances are good that you are not pregnant. If after 2 weeks you have any concerns that you could be pregnant, take a test or see your doctor. Some women have normal pregnancies and have their period every month. But most women are not ovulating (fertile) the day before they start their period. Conception normally occurs mid cycle, day 13 or 14 in a 28 day cycle.
38 weeks before Thursday, August 12th, 2010 = Thusday, November 19th, 2009.
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
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.
Based on a normal gestation period of 40 weeks the conception date was January 20th 2010.
Your pregnancy is considered to have started on the first day of the cycle in which you got pregnant. Since most women have a 28-day cycle and they conceived around the 14th day, you are technically considered 2 weeks pregnant at the time of conception. Therefore, by the time you find out you are pregnant (you've noticed you missed your period, pregnancy test is positive) you are considered about 4 weeks pregnant. hope this is what you were looking for.
