I need some advice PLEASE HELP

[Perbre]

On jan 29 I had unprotected sex  a one night stand .. I remember that on feb 9 th I had a period I don't remember if it was the beginning  the middle or the end I just know I had a period that day ... Then in feb 23 24 and 28 I had unprotected with my current partner .... In march 11 th I found out I was pregnant ... My question is , can there be a chance that the baby is from the  jan 29 guy ... ???

Thank you so much for your advice it was in my mind even tho I have evidence that points out to my current partner I still can stop thinking about it all the time I don't know why :/ but I truly appreciate for answering my doubts :)

This is what the conception calculator says for a due date of November 16.

     First day of last menstrual period:  February 9
     Probable date of ovulation:  February 23
     Possible dates of conception:  February 19 to 27
  
You've got nothing to worry about from the one-night stand on January 29.  Your pregnancy is from your current partner.

I did not have a march period

Hi Annie yes I had an ultrasound today and they said I was 19 weeks and 6 days well 20 by now and my due date is nov 16

Not if the period was a genuine period.  If there was nothing unusual about your period in February (and if it had been odd, you probably would have noticed), you doubtless got pregnant after the period.  Given that your February period included the 9th, did you have a March period?  Or was its absence the reason you tested for pregnancy?  

If you haven't had an ultrasound yet, get one right away.  Even though by now you're 20 weeks along, luckily they don't have to give you pinpoint accuracy, just a due date.  An ultrasound even in your 20th week can distinguish between a baby conceived January 29 and one conceived  February 23, 24 or 28.  When you get the due date, run it through one of the many conception calculators online to get an estimated conception date.  (Keep in mind the doctor will begin the week count with Day 1 of your period, not an assumed day of conception, so use a calculator to get that conception date.)
