breast have gotten bigger. My stomach seems swollen...

I am 21 years old and I recently got back together with my exboyfriend. We are trying to decide if it will work out. I am a college student, not on any type of birth control. Call us stupid but we never use protection. I have only had sex with my ex, we have had two previous birth scares which I just took Plan B and it was fine. However, we had sex a few times one night after drinking and he was 1) not protected 2) he pulled out every time.

**IK this isn't a safe practice but we have never had a problem before

I last got my period mid-June. I am due for another one in about 1-2weeks. However, ever since that night my breast have been VERY tender, they have gotten bigger. My stomach seems swollen. I had clear cloudy urine. I sleep a ton.

Any ideas?
