Who is the father

[Justmez0]

Really need some help on when I would have conceived.. Horrible situation to be in!
I went for a scan on Monday 30th September, they told me I was 7 week & 4 days. The first day of my last period was around Monday 5th August 2019 ended the Thursday/Friday that week.
I slept with my ex partner Sunday 11th & Monday 12th August after my period. I then started sleeping with my new partner from Saturday 17th August and did do for the rest of the month.
This 2 week they add on to pregnancy is really confusing me! Can anyone please help me?
Thank you.

Im so sorry that you thought I was judging you. When I read your opening post I pictured you as being a young teenager and I was wrong about that.

You do what you think is right and can cope with.

I'm sorry you are getting so much negativity OP, that's not what we need when we come for advice.
New (and old) relationships are fraught enough with out the added stress of an early pregnancy and a genetic lottery!
Many women in the same position have just told their preferred partner that the baby is theirs, which you could do and test later (with or without telling him before you get the result)
According to a scientific article I read while at university up to 1/5 of children in uk schools do not have the father that their father thinks they have iyswim, so this situation is VERY much more common than people would have you believe!

Wow some people are really judgemental aren't they! I really feel for you, it's not ideal but it's happened now and if you want to carry on with the pregnancy then that is your choice. Obviously with the dates and not knowing exactly when you ovulated you will need a dna test to be sure, scans are only an estimate and as someone said befor sperm can last up to 5 days so it really is hard to know, but i wish you good luck!!

Difficult situation OP, must be stressful for you! I would say the father is probably the 2nd partner. wishing you a happy and healthy pregnancy xx

It really could be either, you will need a DNA test.

With a normal 28day cycle and assuming you have a normal 14day luteal phase you would have ovulated around the 18th August. Unless you ovulated extremely early in your cycle I’d say it was your new partner. When did you get a positive pregnancy test?

@Ginmonkey84 I took a clear blue on the 6th September and it said 2 -3 weeks on it

@Rose87777 thank you
