Tender breast ,etc.

My EX boyfriend has tried to get me pregnant multiple times now, just so I could stay with him. Majority were forced. For about a week or so now my nipples have been very painful and my breast a little full. Along with nausea and frequently urination. Not a lot though, I just go quicker than usual now. I have 10 days left before AF. What could be some causes for all of this? At first I was nervous. Now I am okay and I don't think about it really anymore. They say your brain can trick you into feeling these things but this has been going on for about 1 1/2-2 weeks. Any advice ?
