Me and my boyfriend broke up.. I met this new guy and later on we had sex on my period the first day November 1st 2013. He came in me.. We stopped talking so me and my ex got back together had sex around the 19 of November and then a week later I find out I'm pregnant.. I'm not sure who the father can be. I did a conception calendar and it said I conceived around the 15-19 of November.. I'm just worried. What do u think?

Is there a third earlier choice ?

The sperm takes two or three days to reach an egg. A pregnancy test done one week after sex, would not show up pregnant.

Even a test done two or three week after sex, normally will not show pregnant.

But it would not be the person, you had sex with one week before the test..

I think you're going to need a DNA test for the little one in about a years time. IT could be either at this point, but it is confusing as to when it could have happened.

If you had a period around 11/1 it is unlikely that you would know for sure around 11/26.

Conception calendars are guesswork so it could be either, but the earlier sex is more likely. But the only way to tell for sure is with DNA testing after the child is born.

I asked a nurse and she said based on the information I had given she said I most likely got peg in the middle of nov

Notice that she said "most likely". Like I said it is an inexact science so that conception dates cannot be calculated exactly.
