I am confused on when I got pregnant. My periods have always been every 27 days. I has sex 9/11/10 and I suppose to had my period on 9/27/10 but I came on 9/22/10. I took home pregancy test on 10/26/10 and it was positve. Did not have a period in October. According to my due date I was 1 week preganant October 3rd so when did I get pregnant. Please someone help me figure this out?

It's impossible for anyone here to tell you when you got pregnant. Some women actually have a period (light) while they are pregnant.

As you get further along, an ultrasound should be able to narrow it down to tell you how far along you actually are.

You are now 17 weeks pregnant.

You are now 17 weeks pregnant.

Not according to the online pregnancy calculator.

LMP was 09.22.2010

That puts the OP at week 15 as of tomorrow.

But there is really no way to have an Exact time, if this was the only time you had sex, it has to be. But at best the doctors timeline is an estimate based on many factors,

It can always be give or take a week or two.

Is there an issue on who the father could be ?

You are now 17 weeks pregnant.

Where do you get your info?

I'm here at work in the Labor and Delivery department. I do this all the time with the same handy dandy gestational wheel that the doctor's use. It was actually given to me by the head OB of the hospital.

With that said, the OP most likely conceived on or around October 6, As of today (January 3) she is exactly 14 weeks and 4 days gestation (I used my L&D computer for that calculation), which gives her a due date of June 29.

If the OP is trying to figure out paternity, it can ONLY be done with a DNA test as this information is only a scientific estimation, not an EXACT science.
