Do you think I'm pregnant

Hi I didn't have my period last month my last period was at the end of May. I also did not get my period this month yet either but I am experiencing symptoms like sore breasts, back pain, and vaginal itchiness and I think I'm gaining weight and have weird new blue veins on the sides of my stomach. I did have protected sex with a condom where my boyfriend pulled out before he came on the 9th and 10th of this month. Do you think that these are pms or pregnancy symptoms???? Since it's two weeks after sex and I don't know when I ovulated or if I did at all I took a pregnancy test and it came back negative.
