Trying to work out when I conceived

[Sm96]

Just to set the scene. My usual period was around the first of the month every month give or take a day or 2. I then had a miscarriage mid April. The following month I had my period mid May. And in June it came 10 days earlier than expected on the 6th. I'm now 23 weeks pregnant. My ovulation day would be the 20th of June this month if my cycle had been the average 28 days. However im aware as a result of my miscarriage and clear irregular cycle that this could be incorrect. My dating scan showed that I did infact conceive around the 20th.

Might I add that I took a test on the 3rd of July which came back negative. I waited overa week to test again and got a positive.

I am wondering if it's possible that I got pregnant on the 13th of June however or if given all these things that it would have been the 20th (approx)?

Is there a reason you need to know? If not don't stress about it. Just be thankful your pregnant :)

Have you had an affair? Im struggling to see why youd be questioning so much if the scan matched your dates??!

No affair its complicated just wondering if people could shed light. Would the test have showed on the 3rd if i did conceive on the 13th? Just need to know really. As I stated due to my previous miscarriage my cycle has been slightly off. And I know scan can be off slightly too so just wondering if all these factors added together made it unlikely it was the 13th

I'm 24 weeks today. I conceived on June 15. I know it's that date because it's an ivf pregnancy.

However. Scans aren't all that accurate - give or take 5 days.

It's unlikely to get a negative on July 3rd if you conceived on the 20th... but it could happen.

Sounds like you might need a dna test??

Just been hoping to rule out dna!
Just to clarify there was no affair or anyrhing of the sorts. I broke up with my ex and slept with someone else a week later! It happens.
Would just make my life a shit ton easier if i didnt have to get involved with my ex again (reasons I don't really need to go into so would rather folk didnt judge)

But thanks for the response. Just think surely if i had conceived on the 13th a test would have shown up by the 3rd if it were positive. I'm aware there are some exceptions however just needed a second or maybe 5th opinion

Likelyhood is I will need a DNA but some reaasurance that it's unlikely I conceived on the 13th is welcome

Sounds unlikely you conceived on 13th

Also might i add the person from the 20th hasn't just been a one off either so would be from 20th onwards.
