mmmhhh I would say that you preagnant from the encounter on the 19th, since sperm can live up to 5 days...

Well the specialist that did my u/s said that i conceived in the beginning of May so are you sure of your answer doesn't seem like you are???

well I am due on Feb 15 and my doctor said my conception day was around May 25, full term pregnancy is 40 weeks if you conceived in the beginning of may and your due date is Feb 13 that makes it around 42 weeks it just doesn't make sense to me, also in a normal pregnancy you should have missed you period on may 15th if you were already pregnant in the beginning of may, if you did conceived in the beginning of may lets say around the 2nd then your due date should be around Jan 29, having short periods does not mean you are going to pregnant for a longer time.

Maybe you're not understanding my questions...I didn't say that I will be pregnant longer becuase I had a shorter period...what I'm asking is when did I conceive before or after my 15th period??? I'm a regular 26 day cycle but the 15th was the only irregular period I've experienced. Then my period stopped...then when I went for two of my u/s both doctor's said that I conceived before the 15th...also in a normal period there's also something called implantation bleeding which might be the possibility for me. Maybe I shouldn't listen to your advice and wait for someone else's.

Thanks anyway

is the advice your doctor is giving you not sufficient enough?

It's sufficient to a certain extent...I've never been pregnant before until now so I'm just confused as to how this whole conception thing works. As you are aware it was with two different guys that I had sexual intercourse with so I'm just trying to figure out exactly when did conception occur if I had an irregular period for the first time in my life and it was shorter with little to no bleeding. It's mainly confusing when you look online at all the calculators telling me that since I started on the 15th then I would've conceived around the 28th or 29th of May but another calculator with the due date information says that I would've started my period on the 9th of May which is so not true. I was supposed to start on the 12th so the very, very first u/s i received the doc said I was 6wks and 4days on the 29th of June but then the specialist said that I was exactly 20 wks in Sept. on I believe the 19th. So she said I conceived in the beginning of May, I requested an amnio just to make sure who the father was but she insisted that my boyfriend is the father and not the guy from the 19th of May.

So basically that's my story summed up...

What do you think???
