Help? I got pregnant straight away

Question

I moved out of my hometown, I broke up with my ex and met a new guy who I ended up having sex with 4 days after knowing him (bc i don’t think) and then I found out that I’m pregnant on the 6th May. 
I did have sex with my ex on the 5th April but I got a period the day after, I had been on the patch for about 1-2 months before I met my new partner. 
I apparently ovulated on the 20th without knowing and that’s when I had sex with my new partner. 
Is this baby my new partners or my ex’s as everyone keeps saying how can it be your current partners baby if you’re 17 weeks and you’ve only been together for 3 months 
I have used so many online calculators and they only say I most probably conceived on the 20th so I think it is my current partners but I need help trying to understand why I’m 17 weeks, I feel like it’s because they automatically add 2 weeks on before you even find out you’re pregnant but I don’t know, everyone’s confusing me and now I don’t know if I’m right or wrong.

Answer

As long as you are sure about your last period, it is not possible to be your ex’s. I would say it is your new partner.

Answer

If the last time you had sex with your ex was before you had a period, then it shouldn’t be him. It would be with someone you had sex with after your last period

Answer

Are you calculating how far along you are based on conception or the first day of your last period? Because where I am, my doctor calculates my due date and how far along I am based on my last period, so technically, there are two weeks included where I wasn’t pregnant. That’s standard practice in the US. You would be considered 4 weeks pregnant even though you ovulated and conceived only two weeks prior.

Answer

Just get a DNA test lol reading this made my head hurt. Probably because I'm tired 😂

Answer

The chances of it being your ex’s are very unlikely

Answer

I realized i was looking at the wrong month in my previous comment 🤦🏻‍♀️🤦🏻‍♀️sorry! 
My due date is jan 26 (according to dating scan-according to last period would be jan 28). Which means you are 2 weeks ahead of me if you are actually 17weeks. But my last period was april 24 and i ovulated may 6th morning(had sex 5th night). So if ultrasound confirmed you are 17weeks for sure then i would say you ovulated around april 22nd so yes its the new guys. What a lucky encounter 😯 congrats mama, when its meant to be its meant to be 🤗 (hope my calculations are on point this time lol....the app doesnt show the ovulation day in the calendar for the month of conception so i was lookin at the previous month by accident)

Answer

Ot would be your exs and what you thought was your period was probably early bleeding in pregnancy, I don't think that it's your new partners considering you are 4months pregnant and only have know your new partner for 3 you are where pregnant before him. And honestly you should get a paternity test because one you can't tell your new partner his the dad because there's only like a 10% chance, and if it is your exs I think that your new partner has the right to know but honestly we can't tell you who's the dad we can only tell you who we think it is based off of right reason, and we can't tell you to get a paternity test because that's your choice but I definitely wouldn't tell new partner he's gonna be a dad if your not for sure. But congratulations mama no matter what your gonna do great your gonna be great no matter who the dad is!! You got this

Answer

Do you know your due date

Answer

It your ex baby you to furlong to be the new guy

Answer

This is my calendar. I think it’s the new partners. Don’t forget they base your weeks on the first day of your last period, not conception date. That’s why it seems a couple off. I’m due January 23
