User :   If I had sex on Aug 27th, 2009 with "guy A" and my period came on for one day (Sept 14) but then I had sex with "Guy B" on sept 26th, 2009 and my due date was june 13th, 2010. Who is the father?
Doctor :   Hi Dr here
User :   hello
Doctor :   let me read ur query
User :   ok
Doctor :   Can u tell me what do u mean by your Due date ? is it the expected date of delivery
User :   Yes, that was the date I received when I went in for an ultrasound but I was induced on June 10th, 2010 due to bad swelling
Doctor :   ok
Doctor :   give me a minute
User :   ok
Doctor :   on the basis of calculation, the second guy, should be the father
User :   How sure are you of that? Even with my cycle coming on for one day on the 14th?
Doctor :   since u already had your period, on sept 14th, even though it was for one day, its likely that the guy B be the father of the child
User :   Ok I just wanted to make sure that the 14th wasn't just because I was bleeding because of implantion or anything
Doctor :   no,
Doctor :   based on calculations, backwards the estimated date of your ovulation is around sept 24th 2009
Doctor :   and since u had sex around sept 27th , he is the likely father
Doctor :   but i would like to know a few things
Doctor :   were u having regular periods before ? and what was the duration of the cycle
User :   yes? what is
User :   that
Doctor :   are u there ?
User :   yes im here?
User :   !
Doctor :   and also calculating forwards
User :   my cycle is usually 3 days
User :   only 3 days
Doctor :   as your LMP is sept 14th, the estimated due date of your delivery had to be around june 15th
Doctor :   i meant , do u have a menstrual cycle of 28 days or more ?
Doctor :   In any case, there is no doubt, that the second guy is the father of the child
User :   um I never knew how to calculate that I just know my cycle only lasted 3 days
User :   last three days on a regular basis
Doctor :   ok
User :   so the 2nd guy sounds more like the father?
Doctor :   like the last date of your bleeding cycle, is the first day of your mentrual cycle
Doctor :   the next time your cycle begins is the last day of your cycle
User :   Ohhh I never knew that, so I guess 28 days would be correct
Doctor :   yes the guy B is the father of yoiur kid
User :   ok thanks alot!
Doctor :   u r welcome
Doctor :   please leave ur feedback as u log out
User :   ok I will do so!
Doctor :   bye for now
