My last month period was a day early it started on the 15, this month im suppose to be starting tomorrow on the 17 but I'm worried if im pregnant I had intercourse on the first week of july. I've only been getting pms cramps, bloating and sore breast.

Have patience... It can be hard to guess whether a woman is pregnant or not. A urine pregnancy test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period, or after having a "weird" period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test.
