Hii my last period was on June 16 I have done sex on 2 July from 2 onwards my stomach is paining a lot I'm pregnant or not tell meee

You are not quite due for your period yet, if it is based on a 28 day cycle. You should be getting it around the 14th of July if I am calculating right. You really can't tell until you miss a period :)

Did you time intercourse around ovulation? This will increase your chances but like star mentioned, you really can't tell until you miss your period.

I agree with the others, no one here can tell you, unfortunately, you get to play the game millions of women around the world get to play, and it is called "waiting". Hope the outcome is as you wish, good luck!
