When did you conceive if due date is June 3?

June 3rd 2010? That would make your conception date roughly September 9th. However, it is difficult to accurately say when a conception date is. Therefore, I suggest talking to your doctor, midwife or obstetrician about it.

When given a dating ultrasound do you need to subtract two weeks for an actual date?

When you have a dating ultrasound you are given an EDD (estimated date of delivery) If you count back 40 weeks from this date it should be about when your last period was. If you do not have a regular cycle they may not correlate exactly. 38weeks back from your EDD is approximately when you conceived.

Can you conceive on day 8 and 15 of a twenty six day cycle?

In order to know what day you can conceive, you will need to know what day you ovulate. Women ovulate at different times, with some cycles being the typical 28 day cycle (with the 1st day of your period being the 1st day of your new cycle), while others may have much longer or shorter cycles.

They now sell ovulation predictor kits over the counter. This will tell you what day you ovulate. In a typical 28 day cycle, you will ovulate around day 14. For a 26 day cycle, you may ovulate earlier--or you may ovulate later. If you ovulate later, then trouble conceiving may be due to a too short luteal phase (the time after you ovulate till your period begins), and you will need to get your progesterone levels checked to see if they are adequate to sustain a pregnancy.

But in a normal, healthy woman with no fertility issues, you would typically begin trying to conceive a couple days after menstruation stopped and until about day 18 (or if using an ovulation predictor kit, until the kit tells you that you have ovulated). These days would cover a typical potential fertile period in normal ovulating women (and includes some extra days, in case of late ovulation). By having sexual intercourse every other day or so during this period, you ensure that sperm is present at the time that the egg is released. This will optimize chances for pregnancy, if no other fertility problems are present.

I am a 9 wks and 6 days pregnant how can I find out date of conception?

What is the difference between intercourse and conception?

Intercourse is the actuual physical act of making love when the sperm is inserted into the vagina. Conception is the moment when the sperm actually fertilises the ovum which may be up to five days later. But unless you are actually being monitored 24/7 there is no way of knowing exactly when conception occurred, hence the up to 5 day variation on US scan

What if your last period is 20 December and your cyecle is 31 days could you conceived a 11 day?

i have learned that you have 14 days since the first day of your period to become pregnant in other words whatever the 14th day lands on that day you become pregnant. for example if you started on the 20th then you were more likely to become pregnant on jan.2 that is when you ovulated.

How do you calculate your conception date if you are three months pregnant?

Hi I found this really helpful site for calculating your conception date. Cut and paste the link into your search bit of your computer and it should come up. Good luck! http://www.intmed.mcw.edu/clincalc/pregnancy.html take your due date. add 3 months to that and then minus 10 days- should give you an approximate within about 2 weeks. for example say youre due date is Feb 24th. Plus 3 months = May 24th - 10 days = May 14th

When did you conceive your ultrasound on January 13 said that you were 35 and half weeks?

When are you fertile the most?

For a woman that has a 28 day cycle days 10 to 16 from the start of her menstruation are the days when she has the best chance of conceiving.

If your due date is February 13 when did you conceive?

May 21 of the prior year would be the approximate date, plus or minus a couple of days or so, as the issue is rarely so well determinable from such an uncertain time as a projected due date, because it is not clear how your due date was determined, and how accurate it is.

See http://www.vaughns-1-pagers.com/biology/gestation-periods.htm.

Nine months less 8 days from conception to delivery is typical (266 days). Thus counting backward nine months from February 13 gives May 13 of the prior year, less 8 days makes the date of conception about May 21 of the prior year, but it could be a couple of days either side of that in actuality.

One can also calculate 280 days, or 40 weeks, from the first day of the woman's last menstrual period. See http://www.betterhealth.vic.gov.au/bhcv2/bhcarticles.nsf/pages/Baby_due_date?OpenDocument

but this does not give you the date of conception, it only relates the due date to the first day of your last menstual period. As this website noted, only 4% of births actually occur on the date predicted.
