When did I conceive?

[Charlottesweb8]

Hello, I am trying to work out the date I conceived, and was wondering if anyone could help/guide.

I ovulated on the 14th & 15th Dec. I had sex on the 15th. The same month I also had sex on the 5/6th and the 19th. My assumption is that it would have been the 15th, but would be keen to know if there is a chance it could have been on one of the other dates.
As an addition, I took the morning after pill on the 20th as I had a brief change of heart about getting pregnant (I’m okay now though!)
Thanks in advance :)

It's much more likely to be the 15th than the 19th. Of course the 19th isn't impossible. What a horrible position to be in OP :(

You have conceived a wanted baby op and the chances of it being the 19th are low.
Don’t be too hard on yourself.

@Charlottesweb8 you will need a DNA test, sperm can live up to 5 days so even if it was the 19th it may still be his.

But an egg is only viable for 24 hours, so sex on 15th is far more likely if that's when you ovulated.

If you ovulated on 15th, 16th or 17th, the egg wouldn't have been viable on 19th.

Good luck with whatever you choose.

But the op doesn't know when she ovulated. If you do an ov stick the day before your period, it will come back positive. It shows a hormone surge, not ovulation itself.

She says she 'definitely ovulated 14th/15th'.

Hey both, yes I thought the ov sticks meant that I was ovulating, but it transpires it most likely means I ovulated 24 hours later. Which is why it's now a little less certain when I conceived. I have an appointment at a wellwomen clinic today to talk this through with a professional.
Thanks all for your input and support, I will update on here when I have one.

No it would not show a positive!

Op you have approx 72 hours from taking a test to get pregnant. Up to 48 hours to ovulate and then another 24 hours for the egg to stay alive. So if you had sex more than 72 hours after a positive opk it’s extremely unlikely that that man is the father.

People post all the time with positive opks before their period hoping they're pregnant. Occasionally they are, usually they aren't. A surge doesn't definitely mean ovulation.

A surge doesn't definitely mean ovulation, and we know there is sometimes a surge just before your period, but is it common to get another surge 3-4 days after your 'normal' ovulation time? Does anyone know?

I think your regular cycles, ovulation tests and morning after pill suggest it's more likely to be your partner's. You can't be certain yet. Does he know about all this?

Just saw an American company that does paternity testing at 7 weeks. I'm sure it costs a lot of money and I don't know if it's available here, but start looking into these options.

Hi all,

I've been looking at the prenatal paternity tests too. There are some that are invasive and some that are done by testing the mothers blood with a swab from the potential father.

Does anyone know about the last option and whether it's legitimate? It all seems to be online organizations rather than actual medical centers which worries me slightly... sorry for changing tract a bit. It's more desirable because you seem to be able to do it earlier than the invasive tests, plus its 100% safe. However if they are less accurate, it might render it pointless...

The American one I saw claimed 99% accuracy. Suppose it depends on the method. Hopefully someone with more experience can point you in the right direction.
