Hi everyone,

I'm 25 weeks pregnant this wed, i'm due September 21st 2016 :) my first day of my last period was between the 16th - 19th dec 2015 i had sex on the 26th dec 2015 and a few times after with my ex from years ago, but i had sex with my partner i'm with now on the 9th jan 2016 i took a test 11 days after that on the 20th jan and i was ofcourse pregnant, my cycle is never longer than 28 days can go from 24-28 though just depends but never longer, is there a chance at all my partner could be the father or 100% my ex's ? xx

I'm sorry, but from all you have said, it seems that it is much more likely that your ex is the dad; January 9 is too late.  Of course, the human body is very mysterious and medicine is more an art than a science, making it worth doing a DNA test with both men so you won't ever have to wonder (don't do a test with only one of the men, test with both).  But it really sounds like you got pregnant a couple of weeks earlier than the 9th of Jan.

Would also like to put i had my first scan on the 15th march i got the due date 21st September i was 12 weeks 6 days took me back to the 16th what is about right as i can't mind when my period start but can mind having them on the 19th dec and a few days after that, everything stayed the same at my 20 week scan also.
