I'm in desperate need for help and I have no one else to talk to.
I am currently 13 weeks and 2 days (ultrasound scan) or 12 weeks 2 day (gestational date). I've been told my due date is 02.10.19 the 1st day of my last period was 02.01.19 but I bleed for a shorter amount of days than usual.

I had sex with my partner 25.12.18 before last period then stupidly with another guy on 08.01.19 (I know)) please dont judge me).

I've had sex with my partner on 09.01.19 and everyday after that until the middle of the following week.

I've looked online with dates etc and what some people have said but it always keeps changing that it could be my partners or the other guy.bi really want it to be my partners so anything before 08.01.19 is preferable or after 12.01.19.

Please is anyone able to help I'd like to know this before it gets too late

Missed this. Impossible to know in this case.

Jame1234 · 29/03/2019 08:02

Jame1234 · 29/03/2019 08:01

On the 8th was with the other guy then 9th 10th 11th 12th etc onwards was with partner

kaytee87 · 29/03/2019 07:59

Take 2 weeks away from the scan dates and that's when you conceived. So it was January.

Karigan195 · 29/03/2019 07:51

There is a pregnancy conception calculator. I put your due date in and this is what you get.

I don’t think you’re going to be able to know on this one without a dna test....

It’s impossible to tell. Measuring babies on scans isn’t an exact science and your due date is only a prediction.

The only way to know is a DNA test.

Notquiteagandt · 29/03/2019 07:48

Fyi just to add confusion sperm can live for a week. I apparently concieved 6 days after I had sex and was other side the world on a trip.

L0kiWh0 · 29/03/2019 07:46

You only count back 38 weeks from your due date. The first two weeks of your pregnancy you’re not actually pregnant, that’s just the time between your period and ovulation.

NoParticularPattern · 29/03/2019 07:46

At conception Hmm

NoParticularPattern · 29/03/2019 07:45

At co caption you are technically about 2 weeks pregnant. 38 weeks back from your due date takes it to the 9th of Jan so it’s not clear from your dates at all who is most likely to be the father. Unfortunately yes, the only way to check is to get a DNA test. I’m not sure if it can be done before the baby is born (amniocentesis etc) but your best (and probably cheapest) bet is to wait until the baby is here and then test, unless it is likely to be obvious at birth who the father is?

TwittleBee · 29/03/2019 07:45

If you count back 40 weeks Jame1234 from your due date you won't get when you conceived but instead the approx time of when your LMP should have been, which is pretty close to your LMP of 2nd Jan. It's common dating scans can be out by a week either way as babies do grow at slightly different rates and it depends on ovulation too.

As previously said, the fertile week for you would have been 7th to 13th according to your dates. So whoever you had sex with between the 7th and 13th January is a possibility of being the father.

Jame1234 · 29/03/2019 07:44

Alright
Thanks

Shostakobitch · 29/03/2019 07:41

There are prenatal DNA tests but you'd need consent from everyone being tested. They are expensive and carry a low risk of miscarriage.

Jame1234 · 29/03/2019 07:38

So I order for me to find out the father the child must be born and DNA test done

ourkidmolly · 29/03/2019 07:35

This can only be sorted by a DNA test after the baby is born. You're going no where with all these calculations.

Jame1234 · 29/03/2019 07:30

Would the 8 to 16 days be after my proper period or the short one?

Jame1234 · 29/03/2019 07:29

Hi
I was told my due date is October 2nd 2019 if I count back 40 weeks from due date wouldn't it make it my partners??? 26th December

L0kiWh0 · 29/03/2019 07:24

Going by a last period of 7/12/18 your due date would be 14th September give or take a few days, so no.

Going by last period of 2/1/19 your due date should be around the 6th October give or take a few days.

It really depends on when you ovulated which is normally 8-16 days after the start of your period, but sperm can live for up to 5 days inside you so it really is going to be impossible to tell giving that the two men you slept with were only a day apart - their speed would be all mixed up inside you so the only way to know is to do a dna test.

Jame1234 · 29/03/2019 06:40

Also thank you to those who have responded you've been very helpful

Jame1234 · 29/03/2019 06:39

So could it of been that after my December period 7th -12th (usual 6 days) 2 weeks later I got pregs???? 26th? Then bleed 2nd to 6th Jan???

Jame1234 · 29/03/2019 06:38

That's what I figured but the mideife/nurse told me you can be pregnant whilst bleeding and that, that period wasnt a 'real' period.... I didnt get that part
