I can't remember my last lmp but I am due in July according to my u/s scan in December I was 10 weeks

I have moved your thread from Olympic Games to Pregnancy and New Motherhood.

When determining due dates we go by your last menstrual cycle rather than when you had sex. Do you remember your LMP?

If that is the only date you have sex, it has to be. Are there other dates you had sex ?

Conception dates and due dates are estimates, They are give or take a week, even two weeks. So really you supply no real info for us to go one, when in Dec did they tell you 10 week ( Dec 1 or Dec 31) Due date by ultrasound go by average sizes, so a fetus that is slightly larger or smaller will make it a incorrect date.

Oh thank you, an I'm sure it was October 7 but can't remember for sure I went for my u/s on the 19th December an I was 10wks3days an due date given was 13th July 2012

No that's not the only time I had sex I had sex a lot of different times its just something happened to me the night of the 24th September an I was wondering if I could have been pregnant from that night thanks for your help

If your due date is July 13, you most likely conceived near the end of October rather than September.

Yh I get told I conceived around 21st October so my u/s wouldn't be that wrong for me to be pregnant by September

No, you most likely did not get pregnant in September.

Ok thanks for all your help but just out of curiosity if I did get pregnant the night in sept when would I have bin pregnant?

If you got pregnant on Sept 24, your due date would be approximately June 17.

Oh thanks for your help that's put my mind at rest as I no they can't b wrong by nearly a month on my due date thanks agen x

You are very welcome!

Another quick question

Sure.

U don't actually get pregnant until around 2 weeks after sex ayit ? So I still wudnt be pregnant until begining of oct so would that still means there's a chance or not sorry for keep asking

You become pregnant when the sperm meets the egg. Typically we ovulate approximately 14 days after our LMP, this is why we go by the LMP to determine due dates.

Once the sperm meets the egg it takes 3-5 days to travel down the fallopian tube and implant into the uterus.

O rite so there still isn't a chance then x

No, not really.

Ok thanks agen

You are very welcome.
