Count back 28 weeks and one day from March 7.
16th August 2008.
You may have conceived in February or March, depending on the regularity of your menstrual cycle.
The statement that you are six weeks pregnant means that you have been pregnant for six weeks, hence, you conceived six weeks ago. Bear in mind that these are estimates, they are not necessarily accurate down to the exact day. But they are reasonably good estimates.
The first day of your pregnancy is the first day of your last menstrual period. At two weeks or so is when you conceive. So when your 4 weeks pregnant your embryo is actually 2 weeks or less old.
Its hard to explain but I will try my best. When you conceive, you are technically two weeks pregnant because doctors consider the last day of your menstrual period to be the first week of pregnancy (even though you really aren't pregnant). You cannot discover pregnancy till about two weeks after being pregnant, so if you find out right away, you are about four weeks pregnant.
pregnancy is dated 40 weeks from the date of your last period. The first day of your last period counted as day one. You usually conceive during the middle of your cycle so when you find out you are pregnant, usually when you miss you next period you are said to be 4 weeks pregnant but the fetus is only actually 2 weeks old.
Doctors measure pregnancy from the first day of your last period, but you don't conceive until two weeks after that. Your baby was conceived 3 weeks ago.
Around June 3rd to June 13th.Your due date is 40 weeks after the first day of your last period.You actually conceive while you are fertile which is usually about 2 weeks AFTER the first day of your last period.So technically, the day you become pregnant, you are usually (medically speaking) 2 weeks pregnant.
If your first day of your period was on Oct.25,2008,then that would make you 18 weeks pregnant(4 months two weeks)and going by that the baby would be born on or around August 1,2009.
March 1, perhaps.
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.
5 weeks and 2 days before that day - give or take a day or two.
