The way doctors count pregnancy, a month pregnant means about two weeks since conception.  

If the ultrasound tech or doctor said you were x weeks x days "pregnant", that count begins on the first day of the last period you had before getting pregnant.

The count is done this way because the period is a big, obvious signal, not because the doctor thinks you are pregnant when you are on day 1 of bleeding.  (He knows you weren't pregnant then, you were having a period!)  That's why pregnancy, which takes 38 weeks, is counted as being 40 weeks long.  They add a spare two weeks at the front to count back to the presumed first day of the last period.  This kind of count was developed in great-grandma's day, before ultrasounds, and the only thing they had for beginning the count was day 1 of bleeding.  Even into the age of ultrasounds, the count remains done this way.

If a doctor sees a woman on July 28 and tells her she is a month pregnant, he means she got pregnant on or around July 14.

I mean June 19,15 me and the other guy had sex with protection but me and my boyfriend had sex July 2,15 with no protection. Could I have gotten pregnant before or after my period.

After me and my boyfriend had unprotected sex July 2,2015 I waited 2 weeks and 2 days took a pregnancy test and it was negative. But if I was a month pregnant like the nurse say wouldn't it be the other guy baby? But we used protection and everything

I understand that you are saying you had sex with one guy on June 19 and another guy on July 2, and a  negative pregnancy test on July 18, that the nurse said you were around 4 weeks pregnant.  But there is no way for me to answer the question of when you conceived except to point out that when a nurse says you are four weeks pregnant, she means only two weeks since conception.  I can't tell you what this means date-wise because you have not said what date it was when the nurse told you that you were a month pregnant.

I understand but I went to the clinic on July 21,15 and that's when the nurse told me I was a month pregnant. I'm just trying to see if my boyfriend the father or is it the other guy
